ABSTRACT:
A low in-rush current power factor control circuit that provides near unity power factor, is capable of controlling and limiting the in-rush current that occurs when the circuit is initially supplied with an AC mains input voltage and is further capable of controlling the DC output voltage of the circuit from a level above to below the peak AC mains input voltage.
