  • Patent number: 8582321
    Abstract: A burst mode control method for a resonant converter is provided, in which at least one first regulation pulse is provided to pre-adjust a magnetizing inductor current and a resonant capacitor voltage in a resonant circuit during a burst mode working period. After the first regulation pulse is completed, at least one pulse group including a plurality of driving pulses is provided to intermittently turn on switching elements of a square wave generator. The first regulation pulse adjusts the magnetizing inductor current and the resonant capacitor voltage, such that the magnitude of the magnetizing inductor current is essentially the same and the magnitude of the resonant capacitor voltage is essentially the same at each rising edge of each driving pulse of the pulse group.
