Research and Design on Digital PFC of 2kW On-board Charger

This paper researches and designs a digital controlled boost power factor correction (PFC) of 2kW on-board charger with the method of continuous conduction mode (CCM), which is based on the DSP of TMS320F280. Multiple-loop control strategy with the instantaneous outer voltage loop and inner current loop is used in the PFC converter. The results confirm that digital controllers are able to be used for high performance PFC converters.
