Abstract
A resonant power converting circuit is provided, which includes a resonant converting unit, a control unit, a voltage detecting unit and a frequency modulation unit. The control unit outputs switching signals to the resonant converting unit to adjust an output of the resonant converting unit. The voltage detecting unit is configured to detect an output voltage of the resonant converting unit. The frequency modulation unit may adjust a lowest switching frequency of the control unit according to the detected output voltage so as to increase a gain of the resonant converting unit and an output stability of the resonant converting unit.
