摘要
A two-phase DC/DC converter includes, as an inductor array, a pair of inductors to which a DC input voltage is alternately applied with a phase difference of about 180 degrees through switching control of switching devices. A duty ratio is substantially in a range from 5% to 40%, and a coupling factor between the inductors is substantially in a range from −0.4 to −0.1. With this configuration, ripple current in the inductors can be made to be smaller than in the case in which there is no coupling between the inductors even when the duty ratio considerably varies.
