Abstract
A semiconductor device drive circuit includes a first drive circuit and a second drive circuit. The first drive circuit generates a control signal for controlling a voltage-controlled switching element. The first drive circuit generates a control signal in synchronization with a voltage signal input to the first drive signal. The first drive circuit has an output current capability corresponding to a magnitude of the voltage signal. The second drive circuit outputs a voltage signal to the first drive circuit. The second drive circuit includes an output adjustment circuit that adjusts the magnitude of the voltage signal.
