The configuration consists of\r\nparallel connected three-phase dc\/ac inverter. Series resistors added\r\nto the inverter output to maintain same current in each inverter of the\r\ntwo parallel inverters, and to reduce the circulating current in the\r\nparallel inverters to the minimum. High frequency third harmonic\r\ninjection PWM (THIPWM) employed to reduce the total harmonic\r\ndistortion and to make maximum use of the voltage source. DSP was\r\nused to generate the THIPWM and the control algorithm for the\r\nconverter. Selected experimental results have been shown to validate\r\nthe proposed system.","references":"[1] I. J.
