Abstract:
This disclosure describes a flyback converter with a series-parallel mode (SPM) active clamp. The active clamp, coupled in parallel with the primary coil, may include a clamp switch, two or more snubber capacitors, and associated diodes. The active clamp may be configured to absorb and retain the leakage energy from the leakage inductance of the flyback converter. The clamp switch may be turned on selectively as the primary switch approaches one of a plurality peak values to adjust frequencies of the switching devices. With the active clamp circuit, the flyback converter may first re-capture the leakage energy in the active clamp circuit and then recover it back to the power source.

Claim (Index 23):
The power conversion apparatus of  claim 22 ,\n wherein the second diode is coupled in parallel with the first capacitor and the first diode, wherein the third diode is coupled in parallel with the second capacitor and the first diode, and wherein the second diode and the third diode are configured to allow a flow of reverse current to discharge the first capacitor and the second capacitor in parallel.
