摘要： A power converter apparatus in which a switched capacitor circuit includes one or more sets of cells connected in series each having a capacitor as a voltage supply source and a bridge circuit for inverting the polarities of the capacitor, the switched capacitor circuit is connected to a load, there is provided a means for parallelly charging the capacitors of the cells with a D.C. voltage source, any number of the cell capacitors are connected in series with any polarity to control supply of an A.C. output to the load. Whereby the power converter apparatus using the switched capacitor circuit can supply A.C. power with less distortion to the load without increasing the withstand voltage of the switching elements and without any need for provision of large inductors or capacitors.
