Abstract

An object is to provide a technique capable of bringing a switching time point of a gate drive condition close to an appropriate switching time point. A semiconductor switching element drive circuit includes a logic circuit that inverts a level of an output signal based on a divided voltage of an output voltage of a semiconductor switching element, and a switching circuit. The switching circuit switches a gate drive condition of the semiconductor switching element during a turn-off operation from a first gate drive condition to a second gate drive condition in which a switching speed is lower than that of the first gate drive condition based on the output signal from the logic circuit.
