Abstract
An object is to suppress an increase in current variation amount of a power storage device. A control device sets an allowable modulation factor, based on a circuit characteristic of a DC part that is on a power storage device side of an inverter, such that a current variation amount of the power storage device becomes equal to or smaller than an allowable current variation amount, and sets switching pattern commands of a plurality of switching elements, based on a set allowable modulation factor.
