ABSTRACT:
A low cost power conversion device operating at a high frequency with high efficiency is realized by using semiconductor switching devices such as FETs being inexpensive and having low withstand voltages and low forward voltage drops. A second error signal obtained by comparing the voltages across two input capacitors connected between both ends of a DC input power supply is subtracted/added from/to a first error signal obtained from a voltage corresponding to a combined DC output of rectifying circuits and the voltage corresponding to a predetermined reference power. Based on the resultant signals, the voltage of a control signal supplied to an inverter circuit in which the voltage across an input capacitor is higher is increased, while the voltage of a control signal supplied to another inverter circuit in which the voltage across another input capacitor is lower is decreased, thereby balancing the voltages across the input capacitors.
