An object is to prevent the motor from carrying out a regeneration braking operation even if any of phase output lines is short-circuited to VB or GND in addition to a short-circuit failure occurring in a MOSFET of an inverter. The semiconductor switching devices of a power conversion apparatus each have a diode that is coupled in parallel to each of the semiconductor switching devices. At least one of the diodes are connected in a direction opposite to the direction in which other diodes are oriented on a current path between the power supply and the ground. Further, at least one of diodes is connected in a direction opposite to the direction in which other diodes are oriented on a current path between the output of the motor and the power supply and on a current path between the output of the motor and the ground.
