Abstract:
Active clamp flyback power converter. At least some of the example embodiments are methods including: activating a main FET and thereby inducing positive current flow in a primary winding, the positive current flow resulting in reverse biasing of a rectifier of a secondary circuit; deactivating the main FET and thereby forward biasing the rectifier in the secondary circuit and causing current flow in the secondary winding; activating a clamp FET and thereby coupling a clamp capacitor to a leakage inductance of a transformer, the primary circuit having initially a positive current flow through the primary winding and then a negative current flow through the primary winding; and regulating the negative current flow through the primary winding.

Claim (Index 16):
The system of  claim 11  further comprising:\n a first timer defined on the substrate, the first timer has a trigger input, a reset input, and a timer output, the trigger input is coupled to the clock signal, and the reset input is coupled to the main drive output; and \n the modulation circuit has a first timer input coupled to the timer output of the first timer; \n wherein when the modulation circuit regulates the clock frequency, the modulation circuit is configured to increase the clock frequency of the oscillator if the signal indicative of negative current through the primary winding falls below a predetermined threshold prior to assertion of the timer output of the first timer.
