Abstract
The present invention provides a resonant converter with a synchronous rectification drive circuit. The resonant converter with the synchronous rectification drive circuit includes a switch circuit, a resonant circuit, a transformer, a full-wave-rectifier circuit and a synchronous rectification drive circuit, wherein the switch circuit at least includes a half-bridge circuit, the resonant circuit is coupled to the switch circuit and has a resonant frequency, the transformer has a primary side coupled to the resonant circuit, the full-wave-rectifier circuit is coupled to a secondary side of the transformer and includes two switches, the synchronous rectification drive circuit includes four voltage-clamped drive circuits having output terminals coupled to the switch circuit and the corresponding switch of the full-wave-rectifier circuit, and each voltage-clamped drive circuit includes a transmission/discharge circuit for reducing the turn-off period of the coupled switch during turning off the coupled switch.
