Abstract

A voltage converter circuit includes rectifier filter circuit, power factor (PFC) converter circuit, full-half bridge resonance converter circuit, voltage regulation control circuit, and voltage feedback control circuit. The PFC converter circuit is configured to convert the rectified and filtered voltage of the rectifier filter circuit to PFC voltage according to first gain. The full-half bridge resonance converter circuit is configured to convert the PFC voltage to a supply voltage according to second gain. The voltage regulation control circuit is configured to generate three voltage regulation signals according to output voltage. The PFC converter circuit is configured to adjust the first gain according to a first voltage regulation signal. The full-half bridge resonance converter circuit is configured to operate in one of three resonance modes according to a second voltage regulation signal. The voltage feedback control circuit is configured to adjust the second gain according to a third voltage regulation signal.
