Abstract
A semiconductor device is subjected to ON/OFF control by controlling a gate voltage according to a drive control signal. In a turn-on operation for charging a gate in response to transition of drive control signal from a first level to a second level, a drive signal is set to first level to discharge the gate at a first time after end of a Miller period of a gate voltage, thereby providing a voltage drop period in which gate voltage temporarily drops. At a second time, drive signal is again set to second level to start charging the gate.
