Abstract
The present disclosure provides a power conversion apparatus converting a power from a DC power source, supplying the converted power to a rotary electric machine to drive the rotary electric machine. The power conversion apparatus according to the present disclosure includes: a first inverter circuit electrically connected to a first end of each of phase winding, transmitting power between respective phase windings and the DC power source; a second inverter circuit electrically connected to a second end each of phase winding, transmitting power between respective phase windings and the DC power source; and a control unit controlling the first inverter circuit and the second inverter circuit. The control unit is configured to change a total amount of current flowing through respective phase windings depending on a rotational speed of the rotary electric machine.
