Abstract
A resonant power conversion device includes a primary side circuit, a frequency detecting circuit, a resonant converting circuit, a secondary side circuit, a secondary detecting circuit, and a control circuit. The primary side circuit receives, according to a control signal having a primary frequency, an input power to output a primary side power. The frequency of the primary side power corresponds to the primary frequency. The frequency detecting circuit detects and converts the primary frequency into a corresponding potential. The resonant converting circuit electrically couples the primary side power to output a resonant power. The secondary side circuit converts the resonant power into a secondary side power. The secondary detecting circuit detects the secondary side power and correspondingly generates a voltage signal. The control circuit outputs the control signal according to the voltage signal, and doesn't output the control signal when the corresponding potential is higher than a predetermined level.
