Abstract
A gate drive circuit includes a signal generation unit configured to generate a first gate drive signal, a signal isolation unit configured to produce, at an output side thereof in response to the first gate drive signal, a second gate drive signal electrically isolated from the signal generation unit, an output stage device configured to receive the second gate drive signal at an input side thereof and to produce a third gate drive signal at an output side thereof in response to the second gate drive signal, a first path connecting the output side of the signal isolation unit and the input side of the output stage device; and a second path connecting the output side of the signal isolation unit and the output side of the output stage device.
