Abstract
A semiconductor module is provided in a power system of an apparatus. The semiconductor module includes a semiconductor switch, a voltage applying device configured to apply a first voltage that is equal to or higher than a rated voltage of the apparatus to the semiconductor switch in an off-state in a case where the apparatus is not in practical use, and a leak detecting circuit configured to detect a leak current from the semiconductor switch. The rated voltage of the apparatus is a rated voltage when the apparatus is in practical use.
