ABSTRACT:
A SEPIC converter powered off line is controlled to improve the input power factor by forcing the current in the input inductor to assume the same wave shape as the voltage across the inductor in series with the power switch to insure a sinewave input current. A switched capacitor is provided to provide brief holdover power to the converter should the input AC voltage fail.
