Abstract:
An active clamp flyback converter includes a transformer, a transistor, a first capacitor, and a second capacitor. The transformer includes a winding. The transistor includes a source terminal that is connected to a first terminal of the winding. The first capacitor includes a first terminal and a second terminal. The first terminal is connected to a drain terminal of the transistor. The second terminal is coupled to a second terminal of the winding. The second capacitor includes a first terminal that is connected to the second terminal of the winding, and is coupled to a second terminal of the first capacitor.

Claim (Index 15):
A power adapter, comprising:\n a transformer having a primary winding, and a secondary winding; a rectifier connected to the secondary winding; a power transistor connected to the primary winding, the power transistor having a gate terminal, having a drain terminal, and having a source terminal; a clamp transistor connected to the primary winding, the clamp transistor having a gate terminal, having a drain terminal, and having a source terminal; and a control circuit coupled to the power transistor and the clamp transistor, the control circuit configured to:\n turn on the power transistor to induce current flow in the primary winding of the transformer; \n responsive to the power transistor being turned off, turn on the clamp transistor for a first interval that is shorter than a time that current flows in the rectifier while the power transistor is turned off; \n turn off the clamp transistor at expiration of the first interval; \n turn on the clamp transistor for a second interval that starts after expiration of the first interval and ends prior to voltage at a source of the clamp transistor falling to zero; and \n turn off the clamp transistor at expiration of the second interval.
