Abstract
According to one embodiment, a control circuit is connected to an element portion including a first element. The first element is an RC-IGBT. The first element includes a first gate, a first other gate, a first collector, and a first emitter. The control circuit performs a first operation and a second operation. In at least a portion of the first operation, the control circuit causes a first current to flow from the first collector toward the first emitter. In at least a portion of the second operation, the control circuit causes a second current to flow from the first emitter toward the first collector. In the second operation, the control circuit supplies a first pulse to the first gate and supplies a first other pulse to the first other gate. The first pulse has a first start time and a first end time.
