Abstract:
Systems for and methods of synchronous rectification in a flyback power converter are disclosed. In accordance with an embodiment, a switching power supply comprises a power converter and a controller. The power converter has an inductor, a capacitor and a switching element. The switching element is configured to rectify a current in the inductor for charging the capacitor to form a voltage for powering a load. The switching element comprises a switch and a diode. The controller is configured to control the switching element and to detect a load condition. When the load condition is detected, the controller controls the switching element to actively rectify the current in the inductor for charging the capacitor. When the load condition is not detected, the controller holds the switching the element open such that the current is passively rectified by the diode.

Claim (Index 21):
A switching power supply comprising:\n a flyback power converter comprising: a transformer having a primary winding and a secondary winding; a capacitor; and a field-effect transistor having a body diode, wherein a switched current in the primary winding induces a current in the secondary winding and wherein the field-effect transistor is configured to rectify a current in the secondary winding of the transformer for charging the capacitor to form a voltage for powering a load; and a controller configured to control the field-effect transistor and to detect a load condition by monitoring a switching frequency in the flyback power converter, wherein when the load condition is detected the controller controls the field-effect transistor to actively rectify the current in the inductor for charging the capacitor, and wherein when the load condition is not detected the controller holds the field-effect transistor element off such that the current is passively rectified by the body diode.
