Beschreibung
Zusammenfassung:	The invention provides a flyback active clamping power converter. The flyback active clamping power converter comprises an input inductor, a lower bridge switch, an upper bridge switch, a first energy storage capacitor, a clamping capacitor, a resonant inductor, an excitation inductor, a transformer, an output diode, and an output capacitor. The resonance frequency generated by the clamping capacitor and the resonant inductor in the fly-back active clamping power converter is essentially equal to the switch switching frequency, and therefore, the output diode can carry out zero current switching (ZCS) within the whole load range.
