Abstract
A gate drive device for driving a switching element includes: a gate drive circuit that drives a gate of the switching element based on a gate drive signal and a drive performance adjustment signal; a gate voltage detection circuit that outputs an on detection signal or an off detection signal when detecting that a gate voltage of the switching element reaches an on determination set value or an off determination set value; and a control circuit that outputs the drive performance adjustment signal to the gate drive circuit to match a gate drive time with a predetermined gate drive time set value.
