Abstract:
Electronic circuitry and method of operating the same to shape and reduce the circulating current through the active clamp in a flyback converter and to harvest most of the leakage inductance energy to provide the bias power. Methodologies for minimizing the circulating energy in the clamp circuit in order to improve efficiency of operation of the same. A method for using a portion of the leakage inductance energy in order to create zero voltage switching conditions at the main primary switch.

Claim (Index 1):
An electronic circuitry having primary and secondary sides and comprising:\n a flyback power converter including\n an input voltage source, \n a transformer having primary and secondary windings, on the primary and secondary sides, respectively, \n a main switch in series with the primary winding on the primary side, and \n a synchronous rectifier in series with the secondary winding on the secondary side, and \n an active clamp circuit across the main switch, the active clamp circuit containing a clamp switch and the clamp capacitor in series with the clamp switch, wherein the clamp switch is configured to be turned on at a moment of time after the main switch is turned off, wherein the clamp switch is configured to be turned off at a moment of time prior to the moment of time at which current passing through the secondary winding reaches a zero level, and wherein the electronic circuitry is characterized by a first value of rms current through the clamp capacitor.
