A method of optimizing the efficiency of an AC-DC converter, wherein the energy extraction time from the AC line is increased and as result the size of the bulk capacitor can be decreased and in applications wherein the size of the bulk capacitor is maintained constant the ripple across the bulk capacitor is decreased. The methods presented also increase the power factor in AC-DC converters. Extending the energy extraction from the AC line also lowers the RMS current through the input bridge and the input bulk capacitor. The reduction of the ripple across the bulk capacitor also increases the efficiency of the DC-DC converter, increasing in this way the overall efficiency of the AC-DC converter.
