摘要：
A gate drive circuit includes a turn-on circuit having an upper limiter for receiving a gate drive signal. The upper limiter has an output terminal. The turn-on circuit also has a transistor having a base connected to the output terminal of the upper limiter. In addition, the terminal has a terminal connected to a gate of a power switching device. The upper limiter limits a voltage input to the base of the transistor to not exceed a first predetermined value.
