Abstract

The present invention discloses a Logic Link Control (LLC) resonance converter control method as well as a synchronous rectification control method and device. The LLC resonance converter control method comprises: judging whether a load works at a preset state according to a switch-on frequency of the input switch tube of a LLC resonance circuit; if yes, making the LLC resonance circuit work at a width modulation control mode; otherwise, making the LLC resonance circuit work at a frequency modulation control mode, wherein the preset state includes a light load state or a no load state. The present invention realizes the voltage stabilization when the LLC resonance circuit is in no load or light load condition, reduces the circuit loss, efficiently simplifies the peripheral hardware circuit and is more reliable to be used in comparison with the traditional technical scheme.
