ABSTRACT:
A one mode of a gate driving circuit that drives a gate electrode of an electric power switching element (9), comprising drive means (6) configured to supply to the gate electrode a current in accordance with a voltage applied across the principal electrodes of the electric power switching element (9), while utilizing a voltage produced by dividing a voltage applied across the principal electrodes by use of resistors (4a,4b). Since the drive means (6) utilizes a voltage produced by a voltage dividing resistor circuit, which divides the voltage applied across the principal electrodes of the electric power switching element (9) as a power source voltage, only an addition of the dividing resistors (4a,4b) makes it possible to constitute the power source for the current drive means (6).
