摘要：
This paper presents the novel driving technique of synchronous rectifier (SR) for the LLC converter. The unique characteristic of "Vo*D=constant" of LLC converter is utilized to predict optimal duty ratio D, where D is the conduction period of secondary diode. This technique does not need the sensing of SR current neither SR voltage. The technique is confirmed by experimentally.
