Theoretically, it takes infinite time to fully charge or discharge a capacitor. The flow of charge is due to electrons having finite and fixed value of charge. If we carefully examine the charging and discharging process after several time constants, the points on q vs t graph become discrete and curve become discontinuous. Moreover for all practical purposes capacitor with charge (q0-e) can be taken as fully charged, as it introduces an error less than one part per million. Similar is the case for discharge of a capacitor, where the capacitor with the last electron (charge e) can be taken as fully discharged. With this, we can estimate the finite value of time for fully charging and discharging a capacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charging" title="charging">charging</a>, <a href="https://publications.waset.org/abstracts/search?q=discharging" title=" discharging"> discharging</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20Circuit" title=" RC Circuit"> RC Circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitor" title=" capacitor"> capacitor</a> </p> <a href="https://publications.waset.org/abstracts/28590/behaviour-of-an-rc-circuit-near-extreme-point" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28590.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1456</span> Innovative Three Wire Capacitor Circuit System for Efficiency and Comfort Improvement of Ceiling Fans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Saket">R.

In this report, a detailed analysis of the energy efficiency of an electric distribution system was carried out with an implementation of the optimal capacitor placement and sizing (OCPS). The particle swarm optimization (PSO) will be used to determine optimal location and sizing for the capacitors whereas energy consumption and power losses minimization will improve the energy efficiency. In addition, a certain number of busbars or locations are identified in advance before the PSO is performed to solve OCPS. In this case study, three techniques are performed for the pre-selection of busbar or locations which are the power-loss-index (PLI). The particle swarm optimization (PSO) is designed to provide a new population with improved sizing and location of capacitors. The total cost of power losses, energy consumption and capacitor installation are the components considered in the objective and fitness functions of the proposed optimization technique. Voltage magnitude limit, total harmonic distortion (THD) limit, power factor limit and capacitor size limit are the parameters considered as the constraints for the proposed of optimization technique. In this research, the proposed methodologies implemented in the MATLAB® software will transfer the information, execute the three-phase unbalanced load flow solution and retrieve then collect the results or data from the three-phase unbalanced electrical distribution systems modeled in the SIMULINK® software. Effectiveness of the proposed methods used to improve the energy efficiency has been verified through several case studies and the results are obtained from the test systems of IEEE 13-bus unbalanced electrical distribution system and also the practical electrical distribution system model of Sultan Salahuddin Abdul Aziz Shah (SSAAS) government building in Shah Alam, Selangor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title="particle swarm optimization">particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-determine%20of%20capacitor%20locations" title=" pre-determine of capacitor locations"> pre-determine of capacitor locations</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20capacitors%20placement%20and%20sizing" title=" optimal capacitors placement and sizing"> optimal capacitors placement and sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20electrical%20distribution%20system" title=" unbalanced electrical distribution system"> unbalanced electrical distribution system</a> </p> <a href="https://publications.waset.org/abstracts/46202/optimal-capacitors-placement-and-sizing-improvement-based-on-voltage-reduction-for-energy-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46202.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1452</span> Implementation of 4-Bit Direct Charge Transfer Switched Capacitor DAC with Mismatch Shaping Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuja%20Askhedkar">Anuja Askhedkar</a>, <a href="https://publications.waset.org/abstracts/search?q=G.%20H.%20Agrawal"> G.

Dynamic Element Matching (DEM) technique is used to match the capacitors. According to element selection logic there are many types.

Among these systems, radial distributions system is popular because of low cost and simple design. In distribution systems, the voltages at buses reduces when moved away from the substation, also the losses are high. The reason for a decrease in voltage and high losses is the insufficient amount of reactive power, which can be provided by the shunt capacitors. But the placement of the capacitor with an appropriate size is always a challenge. Thus, the optimal capacitor placement problem is to determine the location and size of capacitors to be placed in distribution networks in an efficient way to reduce the power losses and improve the voltage profile of the system. For this purpose, in this paper, two stage methodologies are used. In the first stage, the load flow of pre-compensated distribution system is carried out using ‘dimension reducing distribution load flow algorithm (DRDLFA)’. On the basis of this load flow the potential locations of compensation are computed. In the second stage, Genetic Algorithm (GA) technique is used to determine the optimal location and size of the capacitors such that the cost of the energy loss and capacitor cost to be a minimum. The above method is tested on IEEE 9 and 34 bus system and compared with other methods in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dimension%20reducing%20distribution%20load%20flow%20algorithm" title="dimension reducing distribution load flow algorithm">dimension reducing distribution load flow algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=DRDLFA" title=" DRDLFA"> DRDLFA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20distribution%20network" title=" electrical distribution network"> electrical distribution network</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20capacitors%20placement" title=" optimal capacitors placement"> optimal capacitors placement</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20profile%20improvement" title=" voltage profile improvement"> voltage profile improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20reduction" title=" loss reduction"> loss reduction</a> </p> <a href="https://publications.waset.org/abstracts/34573/intelligent-minimal-allocation-of-capacitors-in-distribution-networks-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34573.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1450</span> High Voltage Magnetic Pulse Generation Using Capacitor Discharge Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Adel%20Abdallah">Mohamed Adel Abdallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A high voltage magnetic pulse is designed by applying an electrical pulse to the coil.

There are 3 main types of multilevel inverters (MLI); diode clamped, flying capacitor and cascaded MLI. A cascaded MLI requires the least number of components to achieve same number of voltage levels when compared to other types of MLI while the flying capacitor has the minimum harmonic distortion. However, maximizing the advantage of cascaded H-bridge MLI and flying capacitor MLI, an improved MLI can be achieved with fewer components and better performance. In this paper an improved MLI is presented by asymmetrically integrating a flying capacitor to a cascaded H-bridge MLI also integrating an auxiliary transformer to the main transformer to decrease the total harmonics distortion (THD) with increased number of output voltage levels. Furthermore, the system is incorporated with a hybrid time and climate based solar panel cleaner and power selector which intelligently manage the input of the MLI and clean the solar panel weekly ensuring the environmental factor effect on the panel is reduced to minimum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multilevel%20inverter" title="multilevel inverter">multilevel inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20harmonics%20distortion" title=" total harmonics distortion"> total harmonics distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=cascaded%20h-bridge%20inverter" title=" cascaded h-bridge inverter"> cascaded h-bridge inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=flying%20capacitor" title=" flying capacitor"> flying capacitor</a> </p> <a href="https://publications.waset.org/abstracts/36730/improved-multilevel-inverter-with-hybrid-power-selector-and-solar-panel-cleaner-in-a-solar-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36730.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1448</span> Optimal Capacitor Placement in Distribution Using Cuckoo Optimization Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ravangard">Ali Ravangard</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mohammadi"> S.

They are utilized as sources of reactive power by connecting them in line-to-neutral. Electric utilities have also connected capacitors in series with long lines in order to reduce its impedance. This is particularly common in the transmission level, where the lines have length in several hundreds of kilometers. However, this post will generally discuss shunt capacitors. In distribution systems, shunt capacitors are used to reduce power losses, to improve voltage profile, and to increase the maximum flow through cables and transformers. This paper presents a new method to determine the optimal locations and economical sizing of fixed and/or switched shunt capacitors with a view to power losses reduction and voltage stability enhancement. For solving the problem, a new enhanced cuckoo optimization algorithm is presented.The proposed method is tested on distribution test system and the results show that the algorithm suitable for practical implementation on real systems with any size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor%20placement" title="capacitor placement">capacitor placement</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20losses" title=" power losses"> power losses</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability" title=" voltage stability"> voltage stability</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20distribution%20systems" title=" radial distribution systems"> radial distribution systems</a> </p> <a href="https://publications.waset.org/abstracts/44037/optimal-capacitor-placement-in-distribution-using-cuckoo-optimization-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44037.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1447</span> Electrolytic Capacitor-Less Transformer-Less AC-DC LED Driver with Current Ripple Canceller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasunori%20Kobori">Yasunori Kobori</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Quan"> Li Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Wu"> Shu Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nizam%20Mohyar"> Nizam Mohyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zachary%20Nosker"> Zachary Nosker</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Tsukiji"> Nobukazu Tsukiji</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Takai"> Nobukazu Takai</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruo%20Kobayashi"> Haruo Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an electrolytic capacitor-less transformer-less AC-DC LED driver with a current ripple canceller.

In this paper power consumption is concentrated. The reason for choosing a capacitive sensing is it give slow temperature drift, high sensitivity and robustness. Previous works report a resistive sensing in a voltage control oscillator (VCO) not aiming at power consumption. But this work aims for power consumption of a capacitive sensing in ultra wide band transmitter. The ultra wide band transmitter to be used is a direct modulation of pulses. The VCO which is the heart of pulse generator of UWB transmitter works on the principle of voltage to frequency conversion. The VCO has and odd number of inverter stages which works on the control voltage input this input is now from a variable capacitor and the buffer stages is reduced from the previous work to maintain the oscillating frequency. The VCO is also aimed to consume low power. Then the concentration in choosing a variable capacitor is aimed. A compact model of a capacitor with the transient characteristics is to be designed with a movable dielectric and multi metal membranes. Previous modeling of the capacitor transient characteristics is with a movable membrane and a fixed membrane. This work aims at a membrane with a wide tuning suitable for ultra wide band transmitter.This is used in this work because a capacitive in a ultra wide transmitter need to be tuned in such a way that all satisfies FCC regulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitive%20sensing" title="capacitive sensing">capacitive sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra%20wide%20band%20transmitter" title=" ultra wide band transmitter"> ultra wide band transmitter</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20control%20oscillator" title=" voltage control oscillator"> voltage control oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=FCC%20regulation" title=" FCC regulation "> FCC regulation </a> </p> <a href="https://publications.waset.org/abstracts/15772/an-approach-for-evolving-a-relaible-low-power-ultra-wide-band-transmitter-with-capacitve-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1444</span> Transient Analysis and Mitigation of Capacitor Bank Switching on a Standalone Wind Farm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajibola%20O.%20Akinrinde">Ajibola O.

Standalone wind farms could be a good choice of alternative power generation for such settlements that are far from the grid due to factors of long distance or socio-economic problems. However, uncompensated wind farms consume reactive power since wind turbines are induction generators. Therefore, capacitor banks are used to compensate reactive power, which in turn improves the voltage profile of the network. Although capacitor banks help improving voltage profile, they also undergo switching actions due to its compensating response to the variation of various types of load at the consumer’s end. These switching activities could cause transient overvoltage on the network, jeopardizing the end-life of other equipment on the system. In this paper, the overvoltage caused by these switching activities is investigated using the IEEE bus 14-network to represent a standalone wind farm, and the simulation is done using ATP/EMTP software. Scenarios involving the use of pre-insertion resistor and pre-insertion inductor, as well as controlled switching was also carried out in order to decide the best mitigation option to reduce the overvoltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor%20banks" title="capacitor banks">capacitor banks</a>, <a href="https://publications.waset.org/abstracts/search?q=IEEE%20bus%2014-network" title=" IEEE bus 14-network"> IEEE bus 14-network</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-insertion%20resistor" title=" pre-insertion resistor"> pre-insertion resistor</a>, <a href="https://publications.waset.org/abstracts/search?q=standalone%20wind%20farm" title=" standalone wind farm"> standalone wind farm</a> </p> <a href="https://publications.waset.org/abstracts/40420/transient-analysis-and-mitigation-of-capacitor-bank-switching-on-a-standalone-wind-farm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40420.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">441</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1443</span> Battery/Supercapacitor Emulator for Chargers Functionality Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Farag">S.

Among them, Li-ion capacitors including a negative battery-type lithium intercalation electrode and a positive capacitor-type electrode have achieved tremendous progress and have gone up to commercialization. Inexpensive electrode materials from renewable sources have recently received increased attention since cost is a persistently major criterion to make supercapacitors a more viable energy solution, with electrode materials being a major contributor to supercapacitor cost. Additionally, Na-ion battery chemistries are currently under development as less expensive and accessible alternative to Li-ion based battery electrodes. In this work, we are presenting both lithium and sodium ion capacitor (LIC & NIC) entirely based on electrodes prepared from carbon materials derived from recycled olive pits. Yearly, around 1 million ton of olive pit waste is generated worldwide, of which a third originates in the Spanish olive oil industry. On the one hand, olive pits were pyrolized at different temperatures to obtain a low specific surface area semigraphitic hard carbon to be used as the Li/Na ion intercalation (battery-type) negative electrode. The best hard carbon delivers a total capacity of 270mAh/g vs Na/Na+ in 1M NaPF6 and 350mAh/g vs Li/Li+ in 1M LiPF6. On the other hand, the same hard carbon is chemically activated with KOH to obtain high specific surface area -about 2000 m2g-1- activated carbon that is further used as the ion-adsorption (capacitor-type) positive electrode. In a voltage window of 1.5-4.2V, activated carbon delivers a specific capacity of 80 mAh/g vs. Na/Na+ and 95 mAh/g vs. Li/Li+ at 0.1A /g. Both electrodes were assembled in the same hybrid cell to build a LIC/NIC. For comparison purposes, a symmetric EDLC supercapacitor cell using the same activated carbon in 1.5M Et4NBF4 electrolyte was also built. Both LIC & NIC demonstrates considerable improvements in the energy density over its EDLC counterpart, delivering a maximum energy density of 110Wh/Kg at a power density of 30W/kg AM and a maximum power density of 6200W/Kg at an energy density of 27 Wh/Kg in the case of NIC and a maximum energy density of 110Wh/Kg at a power density of 30W/kg and a maximum power density of 18000W/Kg at an energy density of 22 Wh/Kg in the case of LIC. In conclusion, our work demonstrates that the same biomass waste can be adapted to offer a hybrid capacitor/battery storage device overcoming the limited energy density of corresponding double layer capacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20supercapacitor" title="hybrid supercapacitor">hybrid supercapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=Na-Ion%20capacitor" title=" Na-Ion capacitor"> Na-Ion capacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Ion%20capacitor" title=" Li-Ion capacitor"> Li-Ion capacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=EDLC" title=" EDLC"> EDLC</a> </p> <a href="https://publications.waset.org/abstracts/55801/lithium-and-sodium-ion-capacitors-with-high-energy-and-power-densities-based-on-carbons-from-recycled-olive-pits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55801.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1438</span> Impact of Harmonic Resonance and V-THD in Sohar Industrial Port–C Substation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Al%20Abri">R.

The effect of different laser energy and device bias for waveform on SET was characterized experimentally, as well as the generation and propagation of SET in inverter chain. In this paper, the effects of struck transistors type and struck locations on SETs were investigated. The results showed that when irradiate NMOSFETs from 100th to 2nd stages, the SET pulse width measured at the output terminal increased from 287.4 ps to 472.9 ps; and when irradiate PMOSFETs from 99th to 1st stages, the SET pulse width increased from 287.4 ps to 472.9 ps. When struck locations were close to the output of the chain, the SET pulse was narrow; however, when struck nodes were close to the input, the SET pulse was broadening. SET pulses were progressively broadened up when propagating along inverter chains. The SET pulse broadening is independent of the type of struck transistors. Through analysis, history effect induced threshold voltage hysteresis in PDSOI is the reason of pulse broadening. The positive pulse observed by oscilloscope, contrary to the expected results, is because of charging and discharging of capacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20event%20transients" title="single event transients">single event transients</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20laser" title=" pulse laser"> pulse laser</a>, <a href="https://publications.waset.org/abstracts/search?q=partially-depleted%20silicon-on-insulator" title=" partially-depleted silicon-on-insulator"> partially-depleted silicon-on-insulator</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation-induced%20pulse%20broadening%20effect" title=" propagation-induced pulse broadening effect"> propagation-induced pulse broadening effect</a> </p> <a href="https://publications.waset.org/abstracts/34850/pulsed-laser-single-event-transients-in-018-mm-partially-depleted-silicon-on-insulator-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34850.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1436</span> Reduced Switch Count Asymmetrical Multilevel Inverter Topology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Voodi%20Kalandhar">Voodi Kalandhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Veera%20Reddy"> Veera Reddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuva%20Tejasree"> Yuva Tejasree</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Researchers have become interested in multilevel inverters (MLI) because of their potential for medium- and high-power applications. MLIs are becoming more popular as a result of their ability to generate higher voltage levels, minimal power losses, small size, and low price. These inverters used in high voltage and high-power applications because the stress on the switch is low. Even though many traditional topologies, such as the cascaded H-bridge MLI, the flying capacitor MLI, and the diode clamped MLI, exist, they all have some drawbacks. A complicated control system is needed for the flying capacitor MLI to balance the voltage across the capacitor and diode clamped MLI requires more no of diodes when no of levels increases. Even though the cascaded H-Bridge MLI is popular in terms of modularity and simple control, it requires more no of isolated DC source. Therefore, a topology with fewer devices has always been necessary for greater efficiency and reliability. A new single-phase MLI topology has been introduced to minimize the required switch count in the circuit and increase output levels. With 3 dc voltage sources, 8 switches, and 13 levels at the output, this new single- phase MLI topology was developed. To demonstrate the proposed converter's superiority over the other MLI topologies currently in use, a thorough analysis of the proposed topology will be conducted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-AC%20converter" title="DC-AC converter">DC-AC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-level%20inverter%20%28MLI%29" title=" multi-level inverter (MLI)"> multi-level inverter (MLI)</a>, <a href="https://publications.waset.org/abstracts/search?q=diodes" title=" diodes"> diodes</a>, <a href="https://publications.waset.org/abstracts/search?q=H-bridge%20inverter" title=" H-bridge inverter"> H-bridge inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=switches" title=" switches"> switches</a> </p> <a href="https://publications.waset.org/abstracts/162081/reduced-switch-count-asymmetrical-multilevel-inverter-topology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1435</span> Optimum Locations for Intercity Bus Terminals with the AHP Approach: Case Study of the City of Esfahan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Arabi">Mehrdad Arabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Beheshtitabar"> Ehsan Beheshtitabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahador%20Ghadirifaraz"> Bahador Ghadirifaraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Forjanizadeh"> Behrooz Forjanizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interaction between human, location and activity defines space. In the framework of these relations, space is a container for current specifications in relations of the 3 mentioned elements. The change of land utility considered with average performance range, urban regulations, society requirements etc. will provide welfare and comfort for citizens. From an engineering view it is fundamental that choosing a proper location for a specific civil activity requires evaluation of locations from different perspectives. The debate of desirable establishment of municipal service elements in urban regions is one of the most important issues related to urban planning. In this paper, the research type is applicable based on goal, and is descriptive and analytical based on nature. Initially existing terminals in Esfahan are surveyed and then new locations are presented based on evaluated criteria. In order to evaluate terminals based on the considered factors, an AHP model is used at first to estimate weight of different factors and then existing and suggested locations are evaluated using Arc GIS software and AHP model results. The results show that existing bus terminals are located in fairly proper locations. Further results of this study suggest new locations to establish terminals based on urban criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arc%20GIS" title="Arc GIS">Arc GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=Esfahan%20city" title=" Esfahan city"> Esfahan city</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20locations" title=" optimum locations"> optimum locations</a>, <a href="https://publications.waset.org/abstracts/search?q=terminals" title=" terminals"> terminals</a> </p> <a href="https://publications.waset.org/abstracts/24760/optimum-locations-for-intercity-bus-terminals-with-the-ahp-approach-case-study-of-the-city-of-esfahan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24760.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1434</span> Determination of Suitability Between Single Phase Induction Motor and Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nakarin%20Prempri">Nakarin Prempri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Single-phase induction motors are widely used in industry.

The objective is to minimize the system power loss and to improve bus voltage profile. The optimization problem is subjected to system constraints consisting of load-point voltage limits, radial configuration format, no load-point interruption, and feeder capability limits. A method based on genetic algorithm, a search algorithm based on the mechanics of natural selection and natural genetics, is proposed to determine the optimal pattern of configuration. The developed methodology is demonstrated by a 33-bus radial distribution system with distributed generations and feeder capacitors. The study results show that the optimal on/off patterns of the switches can be identified to give the minimum power loss while respecting all the constraints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20reconfiguration" title="network reconfiguration">network reconfiguration</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation%20capacitor%20placement" title=" distributed generation capacitor placement"> distributed generation capacitor placement</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20reduction" title=" loss reduction"> loss reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/93008/distribution-system-planning-with-distributed-generation-and-capacitor-placements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1432</span> Single-Inductor Multi-Output Converters with Four-Level Output Voltages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasunori%20Kobori">Yasunori Kobori</a>, <a href="https://publications.waset.org/abstracts/search?q=Murong%20Li"> Murong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zhao"> Feng Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Wu"> Shu Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Takai"> Nobukazu Takai</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruo%20Kobayashi"> Haruo Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an electrolytic capacitor-less transformer-less AC-DC LED driver with a current ripple canceller.

The current ripple canceller works as a bi-directional current converter using a sub-inductor, a sub-capacitor and two switches for controlling current flow. LED voltage is controlled in order to regulate LED current by the negative feedback controller using a current sense resistor. There are two capacitors with capacitance of 5 uF. We describe circuit topologies, operation principles and simulation results for our proposed circuit. In addition, we show the line regulation for input voltage variation from 85V to 130V. The output voltage ripple is 2V and the LED current ripple is 65 mA which is less than 20% of the average of LED current of 350 mA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-DC%20buck%20converter" title="DC-DC buck converter">DC-DC buck converter</a>, <a href="https://publications.waset.org/abstracts/search?q=four-level%20output%20voltage" title=" four-level output voltage"> four-level output voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20inductor%20multi%20output%20%28SIMO%29" title=" single inductor multi output (SIMO)"> single inductor multi output (SIMO)</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20converter" title=" switching converter "> switching converter </a> </p> <a href="https://publications.waset.org/abstracts/9207/single-inductor-multi-output-converters-with-four-level-output-voltages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">548</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1431</span> Active Power Flow Control Using a TCSC Based Backstepping Controller in Multimachine Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naimi%20Abdelhamid">Naimi Abdelhamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Othmane%20Abdelkhalek"> Othmane Abdelkhalek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the current rise in the demand of electrical energy, present-day power systems which are large and complex, will continue to grow in both size and complexity.

Thyristor Controlled Series Capacitor (TCSC) is one of FACTS equipment, which is used for power flow control of active power in electric power system and for increase of capacities of transmission lines. In this paper, a Backstepping Power Flow Controller (BPFC) for TCSC in multimachine power system is developed and tested.

The experiment was done in occasion of the presentation of a new bike. A group of dealers has been invited in Lloret de Mar, two persons from the headquarter were present to run the presentation, together with an outsourced trainer. Half day dedicated to the theoretical presentation and half day to the test of the new bike on the road, including the test of its direct competitors. The same presentation, organized in the same way, has been delivered in Italy, in 4 locations often used to run business meetings with dealers. In the end of all days of the presentation, dealers had to fill a questionnaire regarding the evaluation of the different bikes tested. The result of the questionnaire showed how the group invited in Spain rated much higher the new bike compared with the dealers testing the bike in locations already known and close to their home. So, in terms of business strategy, it is important to take into account how the location and the way of presenting any product or service can have a favourable impact on the people we want to convince. The next step of the experiment will be to cross check the sales of that bike with the dealers and measure if there is a relation between the top sellers and the one that appreciated the bike the most, in Spain. It would mean that they were able to transfer to customers the same good feelings and impressions they had in Spain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20presentation" title="product presentation">product presentation</a>, <a href="https://publications.waset.org/abstracts/search?q=locations" title=" locations"> locations</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20effect" title=" emotional effect"> emotional effect</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20strategy" title=" business strategy"> business strategy</a> </p> <a href="https://publications.waset.org/abstracts/76375/the-impact-of-locations-on-the-perception-of-the-same-product-an-application-to-motor-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76375.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1429</span> HPTLC Metabolite Fingerprinting of Artocarpus champeden Stembark from Several Different Locations in Indonesia and Correlation with Antimalarial Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imam%20Taufik">Imam Taufik</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilkatul%20Ilmi"> Hilkatul Ilmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Puryani"> Puryani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mochammad%20Yuwono"> Mochammad Yuwono</a>, <a href="https://publications.waset.org/abstracts/search?q=Aty%20Widyawaruyanti"> Aty Widyawaruyanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artocarpus champeden Spreng stembark (Moraceae) in Indonesia well known as ‘cempedak’ had been traditionally used for malarial remedies.

The aim of this research was to obtain the profile of metabolites that contained in A. champeden stembark from different locations in Indonesia for authentication and quality control purpose of this extract. The profiling had been performed by HPTLC-Densitometry technique and antimalarial activity had been also determined by HRP2-ELISA technique. The correlation between metabolite fingerprinting and antimalarial activity had been analyzed by Principle Component Analysis, Hierarchical Clustering Analysis and Partial Least Square. As a result, there is correlation between the difference metabolite fingerprinting and antimalarial activity from several different growth locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimalarial" title="antimalarial">antimalarial</a>, <a href="https://publications.waset.org/abstracts/search?q=artocarpus%20champeden%20spreng" title=" artocarpus champeden spreng"> artocarpus champeden spreng</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolite%20fingerprinting" title=" metabolite fingerprinting"> metabolite fingerprinting</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20analysis" title=" multivariate analysis"> multivariate analysis</a> </p> <a href="https://publications.waset.org/abstracts/58321/hptlc-metabolite-fingerprinting-of-artocarpus-champeden-stembark-from-several-different-locations-in-indonesia-and-correlation-with-antimalarial-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58321.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1428</span> Order Picking Problem: An Exact and Heuristic Algorithms for the Generalized Travelling Salesman Problem With Geographical Overlap Between Clusters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Rajabighamchi">Farzaneh Rajabighamchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Stan%20van%20Hoesel"> Stan van Hoesel</a>, <a href="https://publications.waset.org/abstracts/search?q=Christof%20Defryn"> Christof Defryn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The generalized traveling salesman problem (GTSP) is an extension of the traveling salesman problem (TSP) where the set of nodes is partitioned into clusters, and the salesman must visit exactly one node per cluster. In this research, we apply the definition of the GTSP to an order picker routing problem with multiple locations per product. As such, each product represents a cluster and its corresponding nodes are the locations at which the product can be retrieved. To pick a certain product item from the warehouse, the picker needs to visit one of these locations during its pick tour. As all products are scattered throughout the warehouse, the product clusters not separated geographically. We propose an exact LP model as well as heuristic and meta-heuristic solution algorithms for the order picking problem with multiple product locations. <p class="card-text"><strong>Keywords:</strong>
