structure of the catalytic converter. Stringent emission regulations around the world necessitate the use of highly-efficient catalytic converters in vehicle exhaust systems. Computational fluid dynamics (CFD) is a powerful tool for calculating the flow field inside the catalytic converter. Radial velocity profiles, obtained by a commercial CFD code, present very good agreement with respective experimental results published in the literature. However the applicability of CFD for transient simulations is limited by the high CPU demands. In the present work, Geometric modeling ceramic monolith substrate is done with square shaped channel type of Catalytic converter and it is coated platinum and palladium. This example illustrates the effect of flow distribution on thermal response of a catalytic converter and different gas flow velocities, during the critical phase of catalytic converter warm up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20converter" title="catalytic converter">catalytic converter</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamic" title=" computational fluid dynamic"> computational fluid dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20media" title=" porous media"> porous media</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20distribution" title=" velocity distribution"> velocity distribution</a> </p> <a href="https://publications.waset.org/abstracts/16814/three-dimensional-simulation-of-the-transient-modeling-and-simulation-of-different-gas-flows-velocity-and-flow-distribution-in-catalytic-converter-with-porous-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16814.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">858</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">844</span> Geometric Optimization of Catalytic Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Makendran">P.

Sanal Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growing severity of government-obligatory emissions legislation has required continuous improvement in catalysts performance and the associated reactor systems. IC engines emit a lot of harmful gases into the atmosphere. These gases are toxic in nature and a catalytic converter is used to convert these toxic gases into less harmful gases. The catalytic converter converts these gases by Oxidation and reduction reaction. Stoichiometric engines usually use the three-way catalyst (TWC) for simultaneously destroying all of the emissions. CO and NO react to form CO2 and N2 over one catalyst, and the remaining CO and HC are oxidized in a subsequent one. Literature review reveals that typically precious metals are used as a catalyst. The actual reactor is composed of a washcoated honeycomb-style substrate, with the catalyst being contained in the washcoat. The main disadvantage of a catalytic converter is that it exerts a back pressure to the exhaust gases while entering into them. The objective of this paper is to optimize the back pressure developed by the catalytic converter through geometric optimization of catalystic converter. This can be achieved by designing a catalyst with a optimum cone angle and a more surface area of the catalyst substrate. Additionally, the arrangement of the pores in the catalyst substrate can be changed. The numerical studies have been carried out using k-omega turbulence model with varying inlet angle of the catalytic converter and the length of the catalyst substrate. We observed that the geometry optimization is a meaningful objective for the lucrative design optimization of a catalytic converter for industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20converter" title="catalytic converter">catalytic converter</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20control" title=" emission control"> emission control</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20systems" title=" reactor systems"> reactor systems</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate%20for%20emission%20control" title=" substrate for emission control"> substrate for emission control</a> </p> <a href="https://publications.waset.org/abstracts/59575/geometric-optimization-of-catalytic-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59575.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">906</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">843</span> Recovery of Hydrogen Converter Efficiency Affected by Poisoning of Catalyst with Increasing of Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enayat%20Enayati">Enayat Enayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Behtash"> Reza Behtash</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the H2 removal system is to reduce a content of hydrogen and other combustibles in the CO2 feed owing to avoid developing a possible explosive condition in the synthesis. In order to reduce the possibility of forming an explosive gas mixture in the synthesis as much as possible, the hydrogen percent in the fresh CO2, will be removed in hydrogen converter. Therefore the partly compressed CO2/Air mixture is led through Hydrogen converter (Reactor) where the H2, present in the CO2, is reduced by catalytic combustion to values less than 50 ppm (vol). According the following exothermic chemical reaction: 2H2 + O2 → 2H2O + Heat. The catalyst in hydrogen converter consist of platinum on a aluminum oxide carrier. Low catalyst activity maybe due to catalyst poisoning. This will result in an increase of the hydrogen content in the CO2 to the synthesis. It is advised to shut down the plant when the outlet of hydrogen converter increased above 100 ppm, to prevent undesirable gas composition in the plant. Replacement of catalyst will be time exhausting and costly so as to prevent this, we increase the inlet temperature of hydrogen converter according to following Arrhenius' equation: K=K0e (-E_a/RT) K is rate constant of a chemical reaction where K0 is the pre-exponential factor, E_a is the activation energy, and R is the universal gas constant. Increment of inlet temperature of hydrogen converter caused to increase the rate constant of chemical reaction and so declining the amount of hydrogen from 125 ppm to 70 ppm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalyst" title="catalyst">catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=converter" title=" converter"> converter</a>, <a href="https://publications.waset.org/abstracts/search?q=poisoning" title=" poisoning"> poisoning</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature "> temperature </a> </p> <a href="https://publications.waset.org/abstracts/28704/recovery-of-hydrogen-converter-efficiency-affected-by-poisoning-of-catalyst-with-increasing-of-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28704.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">819</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">842</span> Experimental Study of Boost Converter Based PV Energy System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Abdelkrim">T.

Lack of the space in many diesel vehicles, however, make it difficult to design and install stand-alone catalytic converters such as DOC, DPF, and SCR in the vehicle exhaust systems. Accordingly, those have been installed inside the muffler to save the space, and referred to the catalytic muffler. However, that has complex internal structure with perforated plate and pipe for noise and monolithic catalyst for emission reduction. For this reason, flow uniformity and pressure drop, which affect efficiency of catalyst and engine performance, respectively, should be examined when the catalytic muffler is designed. In this work, therefore, the flow uniformity and pressure drop to improve the performance of the catalytic converter and the engine have been numerically investigated by changing various design parameters such as inlet shape, porosity, and outlet shape of the muffler using the three-dimensional turbulent flow of the incompressible, non-reacting, and steady state inside the catalytic muffler. Finally, it can be found that the shape, in which the muffler has perforated pipe inside the inlet part, has higher uniformity index and lower pressure drop than others considered in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20muffler" title="catalytic muffler">catalytic muffler</a>, <a href="https://publications.waset.org/abstracts/search?q=perforated%20inlet%20cone" title=" perforated inlet cone"> perforated inlet cone</a>, <a href="https://publications.waset.org/abstracts/search?q=catalysts" title=" catalysts"> catalysts</a>, <a href="https://publications.waset.org/abstracts/search?q=perforated%20pipe" title=" perforated pipe"> perforated pipe</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20uniformity" title=" flow uniformity"> flow uniformity</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20drop" title=" pressure drop"> pressure drop</a> </p> <a href="https://publications.waset.org/abstracts/8517/investigation-of-the-flow-characteristics-in-a-catalytic-muffler-with-perforated-inlet-cone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8517.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">326</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">840</span> A Single Switch High Step-Up DC/DC Converter with Zero Current Switching Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahil%20Samani">Rahil Samani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Soleimani"> Saeed Soleimani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Adib"> Ehsan Adib</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Pahlevani"> Majid Pahlevani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an inverting high step-up DC/DC converter. Basically, this high step-up DC/DC converter is an appealing interface for solar applications. The proposed topology takes advantage of using coupled inductors. Due to the leakage inductances of these coupled inductors, the power MOSFET has the zero current switching (ZCS) condition, which results in decreased switching losses. This will substantially improve the overall efficiency of the power converter. Furthermore, employing coupled inductors has led to a higher voltage gain.

It degrades the performance of a switching converter. Therefore, it is an essential requirement to mitigate EMI noise of high performance converter. Moreover, it includes two types of emission such as common mode (CM) and differential mode (DM) noise. CM noise is due to parasitic capacitance present in a converter and DM noise is caused by switching current. However, there is dire need to understand the main cause of EMI noise. Hence, we propose a novel method to predict conducted EMI noise of different converter topologies during early stage. This paper also presents the comparison of conducted electromagnetic interference (EMI) noise due to different SMPS topologies. We also make an attempt to develop an EMI noise model for a converter which allows detailed performance analysis.

It affects the ecosystem of the environment and also aids to increase the greenhouse effect. The exhaust gases from the automobile is the major cause of a pollution. Automobiles have increased to a large number which has increased the pollution of our world to an alarming rate. There are two methods of controlling the pollution namely, pre-pollution control method and post-pollution control method. This paper is based on controlling the emission by post-pollution control method. The ratio of surface area of nanoparticles to the volume of the nanoparticles is inversely proportional to the radius of the nanoparticles. So decreasing the radius, this ratio is leading resulting in an increased rate of reaction and thus the concentration of the pollution is decreased. To achieve this objective, use of cobalt-graphene element is proposed. The proposed method is mainly to decrease the cost of platinum as it is expensive. This has a longer life than the platinum-based catalysts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automobile%20emissions" title="automobile emissions">automobile emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=catalytic%20converter" title=" catalytic converter"> catalytic converter</a>, <a href="https://publications.waset.org/abstracts/search?q=cobalt-graphene" title=" cobalt-graphene"> cobalt-graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=replacement%20of%20platinum" title=" replacement of platinum "> replacement of platinum </a> </p> <a href="https://publications.waset.org/abstracts/19725/use-of-cobalt-graphene-in-place-of-platnium-in-catalytic-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19725.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">389</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">836</span> A ZVT-ZCT-PWM DC-DC Boost Converter with Direct Power Transfer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naim%20Suleyman%20Ting">Naim Suleyman Ting</a>, <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Sahin"> Yakup Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Aksoy"> Ismail Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a zero voltage transition-zero current transition (ZVT-ZCT)-PWM DC-DC boost converter with direct power transfer.

LEDs are low-voltage light sources, requiring a constant DC voltage or current to operate optimally. LEDs, therefore, require a device that can convert incoming AC power to the proper DC voltage, and regulate the current flowing through the LED during operation. Proposed topology has a front end converter. It is an AC-DC rectifier that works on bridgeless boost topology which shapes the input current waveform. The front end converter is followed by a DC-DC converter which provides a constant DC voltage across the LEDs. A 12V AC input is given to the input of frontend converter which rectifies and boost the voltage to 24v DC and gives it to the DC-DC converter. The DC-DC converter converts the 24V DC and regulates this constant DC voltage across the LEDs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridgeless%20rectifier" title="bridgeless rectifier">bridgeless rectifier</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20factor%20correction%28PFC%29" title=" power factor correction(PFC)"> power factor correction(PFC)</a>, <a href="https://publications.waset.org/abstracts/search?q=SC%20converter" title=" SC converter"> SC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20harmonic%20distortion%20%28THD%29" title=" total harmonic distortion (THD)"> total harmonic distortion (THD)</a> </p> <a href="https://publications.waset.org/abstracts/53400/analysis-of-a-power-factor-correction-converter-for-light-emitting-diode-driver-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53400.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">873</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">834</span> Double Fourier Series Applied to Supraharmonic Determination: The Specific Cases of a Boost and an Interleaved Boost Converter Used as Active Power Factor Correctors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erzen%20Muharemi">Erzen Muharemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20De%20Jaeger"> Emmanuel De Jaeger</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%20Knockaert"> Jos Knockaert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work presented here investigates the modeling of power electronics converters in terms of their harmonic production.

The program was written in Python. Various parameters pertaining to the operation of the converter can be modified by the configuration program through the Ethernet interface of the converter. The converter supports 3 representative asynchronous serial communication protocols, RS-232, RS-422, and RS-485 and supports 3 network modes, TCP/IP server, TCP/IP client, and UDP client. The TCP/IP and UDP protocols were implemented on the microcontroller using an open source TCP/IP protocol stack called lwIP (A lightweight TCP/IP) and FreeRTOS, a free real-time operating system for embedded systems. Due to the use of a real-time operating system, the firmware of the converter was implemented as a multi-thread application and as a result becomes more modular and easier to develop. The converter can provide a seamless bridge between a serial port and an Ethernet port, thereby allowing existing legacy apparatuses with no Ethernet connectivity to communicate using the Ethernet protocol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=converter" title="converter">converter</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20systems" title=" embedded systems"> embedded systems</a>, <a href="https://publications.waset.org/abstracts/search?q=ethernet" title=" ethernet"> ethernet</a>, <a href="https://publications.waset.org/abstracts/search?q=lwIP" title=" lwIP"> lwIP</a>, <a href="https://publications.waset.org/abstracts/search?q=UART" title=" UART"> UART</a> </p> <a href="https://publications.waset.org/abstracts/83695/an-implementation-of-a-configurable-uart-to-ethernet-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83695.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">706</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">831</span> Reaction Rate Behavior of a Methane-Air Mixture over a Platinum Catalyst in a Single Channel Catalytic Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doo%20Ki%20Lee">Doo Ki Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kumaresh%20Selvakumar"> Kumaresh Selvakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Man%20Young%20Kim"> Man Young Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Catalytic combustion is an environmentally friendly technique to combust fuels in gas turbines. In this paper, the behavior of surface reaction rate on catalytic combustion is studied with respect to the heterogeneous oxidation of methane-air mixture in a catalytic reactor. Plug flow reactor (PFR), the simplified single catalytic channel assists in investigating the catalytic combustion phenomenon over the Pt catalyst by promoting the desired chemical reactions. The numerical simulation with multi-step elementary surface reactions is governed by the availability of free surface sites onto the catalytic surface and thereby, the catalytic combustion characteristics are demonstrated by examining the rate of the reaction for lean fuel mixture. Further, two different surface reaction mechanisms are adopted and compared for surface reaction rates to indicate the controlling heterogeneous reaction for better fuel conversion. The performance of platinum catalyst under heterogeneous reaction is analyzed under the same temperature condition, where the catalyst with the higher kinetic rate of reaction would have a maximum catalytic activity for enhanced methane catalytic combustion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20combustion" title="catalytic combustion">catalytic combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20reaction" title=" heterogeneous reaction"> heterogeneous reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=plug%20flow%20reactor" title=" plug flow reactor"> plug flow reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20reaction%20rate" title=" surface reaction rate"> surface reaction rate</a> </p> <a href="https://publications.waset.org/abstracts/77722/reaction-rate-behavior-of-a-methane-air-mixture-over-a-platinum-catalyst-in-a-single-channel-catalytic-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77722.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">273</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">830</span> A Single Phase ZVT-ZCT Power Factor Correction Boost Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Sahin">Yakup Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Naim%20Suleyman%20Ting"> Naim Suleyman Ting</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Aksoy"> Ismail Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a single phase soft switched Zero Voltage Transition and Zero Current Transition (ZVT-ZCT) Power Factor Correction (PFC) boost converter is proposed.

The usage of this kind of converters come from its advantage of non-reverse polarity at outputs. As capacitors charge and discharge through inductance, peak current does not occur on capacitors. Therefore, the efficiency will be high compared to buck-boost converters. In this study, the converter (SEPIC) is designed to be operated with Internal Model Controller (IMC). The traditional controllers like Proportional Integral Controller are not preferred as its linearity behavior. Hence IMC is designed for this converter.

The proposed converter employs only a single power switch instead of using several switches. Compared to the conventional DC-DC step-up converters the higher voltage gain with small output ripples can be achieved by using the proposed high step-up DC-DC converter topology. It can step up the low input voltage (20-50Vdc) generated from the photovoltaic modules to the high output voltage level approximately 600Vdc in order to supply the three-phase inverter fed the three-phase motor drive. In this paper, the operating principle of the proposed converter topology and its control strategy under the continuous conduction mode (CCM) are described. Finally, simulation results are shown to demonstrate the effectiveness of the proposed high step-up DC-DC converter with its control strategy to increase the voltage step-up conversion ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-DC%20converter" title="DC-DC converter">DC-DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20step-up%20ratio" title=" high step-up ratio"> high step-up ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20switch" title=" single switch "> single switch </a> </p> <a href="https://publications.waset.org/abstracts/9443/a-high-step-up-dc-dc-converter-for-renewable-energy-system-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9443.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">1193</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">824</span> The Catalytic Activity of CU2O Microparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanda%20Wongwailikhit">Kanda Wongwailikhit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Copper (I) oxide microparticles with the morphology of cubic and hollow sphere were synthesized with the assistance of a surfactant as the shape controller.

In the cascade boost family, quadratic boost converter is the best trade-off when circuit complexity and modulator saturation is considered. Sliding mode control being a nonlinear control results in a robust and stable system when applied to switching converters which are inherently variable structured systems. The stability of this system is analyzed through Lyapunov’s approach. Analysis is done for load regulation, line regulation and step response of the system.

The switch commutation arrangements are also carried out in this work. The SPMC topology has many advantages as a minimal passive device use. It is very flexible and it can be used as a lot of converters. The gate pulses to the switches are provided by the PWM techniques.

The approach is based on a behavioural description of the different operating modes of the converter. Each operating mode represents a well-defined configuration, and for which is matched an operating zone satisfying given invariance conditions, depending on the capacitors' voltages and the load current of the converter. For each mode, a control vector whose components are the control signals to be applied to the converter switches has been associated. Therefore, the problem is reduced to a classification task of the different operating modes of the converter.
