Abstract :
This paper presents a digital controller for boost power factor correction (PFC) converter. The digital controller features an optimal digital current compensator and a novel current-loop feed-forward (CFF) compensation. The CFF compensation can improve power factor without increasing the current-loop gain and bandwidth. Experiment results are shown to validate the design approach.
