ABSTRACT:
A resonance-type power switching device includes: a power controller for producing a power control pulse, main and auxiliary switches for generating switching power in response to the power control pulse, and a control pulse advancing circuit for advancing the generation of the power control pulse by a preset time interval and for supplying the advanced generation of the power control pulse to the auxiliary switch in advance, such that a drive signal is generated to provide an off time interval between the turn-on of the main switch and the turn-on of the auxiliary switch to effect resonance during the off time interval.
