POWER CONVERSION APPARATUS

A power conversion apparatus includes a power converter configured to convert DC power supplied from a battery into AC power by switching control, and is configured to supply the AC power from the power converter to a rotary electric machine having windings. Further, the power conversion apparatus includes a control unit that performs temperature-increase control of the battery by performing switching control of upper arm switches and lower arm switches so that a current flows to the battery via the power converter and the windings. In the temperature-increase control while the vehicle is stopped, the control unit controls the current so that a current value of the rotary electric machine gradually increases within a current control range in which a torque of the rotary electric machine is less than an upper limit torque.
