Abstract

A driving circuit and a switch signal generation method are provided. The driving circuit receives a PWM signal and provides a first switch signal and a second switch signal. The driving circuit includes a logical signal circuit, a lower bridge dead time circuit and a lower bridge driving circuit. The logical signal circuit provides a first logical signal and a second logical signal according to the PWM signal. The lower bridge dead time circuit determines a leading edge of a lower bridge dead time signal according to the first logical signal and determines a trailing edge of lower bridge dead time signal according to a trailing edge of first switch signal. The lower bridge driving circuit determines a leading edge of second switch signal according to second logical signal and determines a trailing edge of second switch signal according to the trailing edge of lower bridge dead time signal.
