Abstract
A semiconductor switching device includes a power control part, which includes a voltage dropping chopper circuit having a first switching element and a first diode, a voltage boosting chopper circuit having a second switching element and a second diode, and an inductance. And the inductance is connected such that an unusual current caused by the arm short circuit is forced to pass through the inductance.
