Abstract

A resonant converter (1) is provided. The detection circuit (7) detects the voltage and/or the current of the output terminal (Vo, VoL). The controller (8) controls the startup frequency of the two first switches (Q1, Q2) and the two second switches (Q3, Q4) according to the voltage and/or the current of the output terminal (Vo, VoL) detected by the detection circuit (7). The soft startup procedure is executed. Consequently, the switching stress of the synchronous rectifier circuit (6) is reduced. The resonant converter (1) of the present disclosure has advantage of enhancing lifespan, enhancing efficiency and enhancing stability of the system.
