The buck-boost power factor corrected (PFC) converter has wide range of the DC output voltage. In this paper, the application for the V-connected inverter to reduce the cost of the inverter is proposed. First the balance of series connected smoothing capacitor voltage is discussed. Next, double converter configuration to reduce the input current ripple is discussed. Finally, a soft-switching method...
OSAKA converter, which is a large scale three-phase soft-switching power factor corrected converter, is proposed. The converter switches once in every half cycle of an AC commercial power source. Therefore, it can solve many problems caused by the high frequency operation. The proposed converter achieves the soft-switching operation and the EMI noise can be reduced. In this circuit, resonant capacitor,...
