<p>According to the present invention, switches (S1, S2) perform switching at a timing when a first phase voltage (Vinv1) and a second phase voltage (Vinv2) outputted from a three-phase voltage source (12) have a phase difference of 90°. Then, a three-phase/two-phase conversion inductor (14) outputs two pairs of AC currents (Iinv1, Iinv2), and a rectification and a single-phase pulse-width modulation are performed on each of AC currents (i1, i2). Modulated currents (m12, m34) obtained as a result of the rectification and the single-phase pulse-width modulation are synthesized, to generate an output current (mi), which is supplied to a circuit (90) in which a capacitor (20) and a load (92) are connected in parallel with each other.</p> |
