Abstract
A power conversion apparatus includes an inverter for drive controlling a plurality of switching elements, drive circuits, a control circuit, a current detection part, an overcurrent detection circuit, and a protection circuit. The protection circuit, which receives a detection signal that the overcurrent detection circuit outputs to indicate detection of overcurrent, outputs a signal to the drive circuits for turning off a switching element that has been turned on by a control signal from the control circuit for a predetermined time.
