PROBLEM TO BE SOLVED: To eliminate a possibility of electrical connection generated simultaneously between a p-type MOSFET and an n-type MOSFET for driving the main switching element. SOLUTION: In a gate drive circuit, when one of a p-type MOSFETQ1 and an n-type MOSFETQ2 for driving the main switching element is turned on and another is turned off, the main switching element is turned on; and, when one is turned off and another is turned on, the main switching element is turned off. In a case that one is switched ON from OFF and another is switched OFF from ON, ahead of the moment that one is switched ON from OFF, another is switched ON from OFF, one is switched OFF from ON. In a case that another is switched ON from OFF, ahead of the moment that another is switched ON from OFF, one is switched OFF from ON. COPYRIGHT: (C)2007,JPO&INPIT
