摘要: A high voltage drive circuit includes an edge detector for generating an edge detection signal by detecting edges of a first high side input signal and a first low side input signal, the edge detector providing a high side delay signal and a low side delay signal by delaying the first high side input signal and the first low side input signal, a dead time generator for generating a dead time signal indicating a preset dead time in response to the edge detection signal, and a driver comprising a drive signal generator for providing a high side output signal and a low side output signal by inserting the preset dead time based on the dead time signal into the high side delay signal and the low side delay signal.
