Abstract
This application relates to a wide band gap (WBG) power semiconductor system. In one aspect, the system includes a controller configured to generate a switching control signal and a gate driver configured to receive the switching control signal and generate a switching drive signal in response to the switching control signal. The system also includes a WBG power semiconductor device coupled to the gate driver, comprising a gate terminal for receiving the switching drive signal, and configured to be switched in response to the switching drive signal. The switching drive signal has one of three signal levels: a first voltage level higher than a zero voltage level, a second voltage level lower than the zero voltage level, and the zero voltage level at an arbitrary instant. As a result, the gate driver drives the WBG power semiconductor device with the three voltage levels.
