Zusammenfassung:	PROBLEM TO BE SOLVED: To realize a high voltage semiconductor switch drive circuit which assures high speed operation with an arbitrary pulse width with an extremely simplified circuit structure. SOLUTION: A high voltage semiconductor switch element 5 for receiving a pulse voltage obtained from a pulse transformer at a gate of a capacitive load via a diode 3 is connected in a high voltage current circuit and a second switch element 4 is also connected to the diode 3 discharge, when the pulse voltage falls, the charges of a gate capacitor charged when the pulse voltage rises.
