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 1):
In an active clamp flyback power converter including a primary circuit with a main field effect transistor (FET), a clamp FET, and a primary winding of a transformer, and the power converter including a secondary circuit comprising a secondary winding of the transformer and an active or passive rectifier, a method comprising:\n activating the main FET and thereby inducing a positive current flow in the primary winding, the positive current flow resulting in reverse biasing of the rectifier of the 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 the clamp FET and thereby coupling a clamp capacitor to a leakage inductance of the 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.
