An Original Digital PFC Technique with Non-sinewave Current

The digital PFC techinque using a standard microcontroller to implement PFC control and regulation, allows the non-sinewave current drawn from the mains to he synthesised and to adapt its amplitude to partieular requirement This method enable the current harmonic content lo stay under the limits fixed by the standard and the global power factor is very close to L. Other features can also be implemented such as fast current loop, voltage regulation, safety fuetions.
