<p>In the disclosed interleaved power factor correction circuit, which uses a boost chopper, the tradeoff between increased efficiency and audible sound suppression is improved by means of appropriately setting the characteristics of an inductor. An inductor (L1), diode (D1), and switching element (S1), which are connected to a pathway (LH1), configure a boost circuit (B1); and an inductor (L2), diode (D2), and switching element (S2), which are each connected to a pathway (LH2), configure another boost circuit (B2). The boost circuits (B1, B2) also function as power factor correction circuits that improve the power factor of the input side. Swinging chokes are utilized as the inductors (L1, L2).</p> |
