  "textContent": "A power conversion apparatus (10) includes a power converter (30) configured to convert DC power supplied from a battery (20) into AC power by switching control, and is configured to supply the AC power from the power converter to a rotary electric machine (40) having windings (41). Further, the power conversion apparatus (10) includes a control unit (70) that performs temperature-increase control of the battery by performing switching control of upper arm switches (QUH, QVH, QWH) and lower arm switches (QUL,QVL,QWL) 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.",
