A PFC circuit is provided. A first bridge rectifier receives an AC voltage. A power converter includes a switch and receives an output of the first bridge rectifier, converts the output to a first DC voltage, and supplies the first DC voltage to a DC bus to power a compressor. A second bridge rectifier receives the AC voltage and bypasses at least one of the first bridge rectifier, a choke and a diode of the PFC circuit to provide a rectified AC voltage out of the second bridge rectifier to the DC bus to power the compressor. A control module controls operation of a driver to transition the switch between open and closed states to adjust a second DC voltage on the DC bus, where the second DC voltage, depending on the AC and second DC voltages, is based on the first DC voltage or the rectified AC voltage.
