Power Conversion Device

Abstract: Provided is a power conversion device comprising: a control unit that performs PWM control on switching elements of an inverter circuit (5) for driving a multiphase AC motor (10); a current detection means (7) that detects in each phase a current flowing to the motor (10); an A/D conversion means that converts a detected current detection signal into a digital signal and performs current value detection processing; and a current detection phase selection means (8) that selects the current detection signal detected by the current detection means (7) and sets the timing of the current value detection processing performed by the A/D conversion means within one cycle of a PWM carrier wave on the basis of a voltage instruction value or a duty ratio setting value.
