Power converter

摘要

A power converter has two switched capacitor circuits each including at least a plurality of sets of capacitors and switching elements, first of which circuits is provided for supplying a DC power to a load while second of which accumulates a power in a period receiving a higher input voltage, and the first switched capacitor circuit being made to receive, in a period receiving a lower input voltage, a power supplied from a DC power source and also the power supplied from the second switched capacitor circuit for supplying to the load the DC power of a constant voltage, in which an input current collectively taken up by the two switched capacitor circuits is made similar in the waveform to the input voltage to eliminate any harmonics distortion of the current drawn from the source, for attaining the supply of the DC power of the constant voltage to the load, whereby the power converter is rendered not to require any large inductor to be capable of being minimized in size and restraining any noise radiation from occurring.
