Abstract
A multi-phase power device for driving an inductive load includes a first semiconductor device and a second semiconductor device connected in series in each of three phase arms. Each first semiconductor device includes a first switching device made of a wide-bandgap semiconductor and a freewheeling diode that is made of a narrow-bandgap semiconductor and is connected in anti-parallel to the first switching devices. Each second semiconductor device includes a second switching devices made of a wide-bandgap semiconductor and a freewheeling diode connected in anti-parallel to the second switching device.
