Abstract
A switching circuit includes a wiring into which a parallel circuit of a first IGBT and a second IGBT is inserted, and a gate control circuit. The gate control circuit has a first switching element configured to control a gate potential of the first IGBT according to a potential of a second principal electrode, and a second switching element configured to control a gate potential of the second IGBT according to a potential of a fourth principal electrode. An output terminal of the control device is connected to the first switching element through a first switch and is connected to the second switching element through a second switch. The control device applies a control signal to the output terminal in a state where the first switch and the second switch are turned on when switching both of the first IGBT and the second IGBT.
