<p>Switches (S1, S2) perform switching at such a timing as the phase difference between a first phase voltage (Vinv1) and a second phase voltage (Vinv2) outputted from a three-phase voltage source (12) becomes 90 degree. Subsequently, a three-phase/two-phase inductor (14) outputs two sets of AC current (Iinv1, Iinv2) and AC currents (i1, i2) are subjected, respectively, to rectification and single-phase pulse width modulation. An output current (mi) is created by synthesizing modulation currents (m12, m34) subjected to rectification and single-phase pulse width modulation, and supplied to a circuit (90) where a capacitor (20) and a load (92) are connected in parallel.</p> |
