Abstract
A switching circuit may include first and second switching elements that are connected in parallel with each other. A controller may be configured to selectively perform either a first switching control to drive the first switching element or a second switching control to drive the second switching element. The first switching element may be constituted mainly of a first semiconductor material, and the second switching element may be constituted mainly of a second semiconductor material having a narrower band gap than the first semiconductor material. The second switching element may be larger in size than the first switching element. The controller may be configured to switch to the second switching control when an instruction value and/or an actual value of the current exceeds a predetermined threshold value while performing the first switching control.
