Abstract
Switches perform switching at a timing when a first phase voltage and a second phase voltage outputted from a three-phase voltage source have a phase difference of 90°. Then, a three-phase/two-phase conversion inductor outputs a pair of AC currents, and a rectification and a single-phase pulse-width modulation are performed on each of AC currents. Modulated currents obtained as a result of the rectification and the single-phase pulse-width modulation are synthesized, to generate an output current, which is supplied to a circuit in which a capacitor and a load are connected in parallel with each other.
