Kind Code:
A1
Abstract:
A control unit of the power conversion device of the present disclosure makes a first carrier wave signal and a second carrier wave signal different from each other when an AC rotating machine is in a power running operation state, makes the first carrier wave signal and the second carrier wave signal equal to each other when the AC rotating machine is in a regenerative operation state, and controls a first power converter and a second power converter in a region in which power generation current flowing from the AC rotating machine to a DC power supply monotonically increases with respect to a regenerative torque.
