Abstract :
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 of the buck-boost PFC converters when the system operates in the discontinuous current mode (DCM) is proposed.
