Abstract
A controlling circuitry of a power conversion device has a first control mode for controlling circulation current circulating among leg circuits for the respective phases in a power converter so that an AC component having a frequency that is an even multiple other than a multiple of 3 with respect to the frequency of a fundamental component of AC is contained in the circulation current, and determines whether to make the first control mode active or inactive, on the basis of the voltage value of an energy storage element.
