Abstract
The present disclosure relates to a power converter device including a power factor correction circuit, a resonance converter circuit, and a zero voltage switching circuit. The power factor correction circuit is coupled to the primary side rectifier circuit, and includes a first switching circuit, a first control circuit and a first output circuit. The resonance converter circuit includes a second switching circuit and a second control circuit. The second switching circuit is coupled to the first output circuit, and the second control circuit is coupled to the secondary side rectifier circuit. The zero voltage switching circuit is coupled between the first control circuit and the second control circuit. The zero voltage switching circuit is configured to obtain a switching voltage of a switch element in the second switching circuit, and output an adjustment signal to the first control circuit according to the switching voltage.
