Abstract

A phase difference correction control unit determines, based on a difference between a voltage of a first input smoothing capacitor and a voltage of a second input smoothing capacitor, a difference between a current flowing through a first switching element and a current flowing through a second switching element, or a difference between a reactor current when a gate signal of the first switching element is turned on and a reactor current when a gate signal of the second switching element is turned on, an amount of correction of a difference between a phase of switching of the first switching element and a phase of switching of the second switching element. A switching control unit switches the first switching element and the second switching element based on the amount of correction.
