ABSTRACT:
A high-power factor series resonant rectifier circuit comprising a first rectifier for rectifying an AC input power, a push-pull switching circuit for changing a polarity in the output of the first rectifier in response to a resonant frequency, an isolation transformer for transforming the output of the push-pull switching circuit, an LC resonance tank for resonating the output of the isolation transformer, a second rectifier for rectifying the output of the LC resonant tank, and a boost chopper switch connected in parallel to the output of the second rectifier. The boost chopper switch performs a switching operation when a resonant current becomes zero, resulting in an increase in power density. The increase in power density results in a reduction in switching loss. Therefore, the rectifier circuit of the present invention is operable at a high frequency.
