Zusammenfassung:	According to an embodiment, an inspection apparatus inspects an inverter circuit including three pairs of arms. The apparatus includes a current controller and a control signal generator. The current controller generates a control output for controlling a current to be output by the inverter circuit. The control output enables the current to approach a target value of the current. The control signal generator generates a first control signal for controlling ON/OFF of a first arm as one of the three pairs of arms based on the control output, a second control signal for fixing a second arm paired with the first arm, in an OFF-state, and a third control signal for fixing at least part of arms other than the first arm and the second arm in an ON-state.
