Abstract

A power converting system rendering an applied voltage to a load to be a continuous voltage waveform, wherein a plurality of capacitors are charged so that their terminal voltages will reach predertermined voltages mutually different, the respective capacitors are sequentially connected respectively through a switching element to a series circuit of an inductor and a load-use capacitor, the load-use capacitor is charged with a resonance current of the capacitor and inductor, and the applied voltage to the load-use capacitor is made to be a pulsating waveform by properly adjusting the terminal voltages upon charging of the respective capacitors as well as change-over timing of the respective switching elements.
