Abstract
Reduced voltage switching of the primary switch. At least one example is a method comprising: activating, during a first switching period, a primary switch coupled to a primary winding of a transformer of a flyback topology, the activating induces a positive current in the primary winding; deactivating the primary switch and activating a secondary switch coupled to the secondary of the transformer, the activating the secondary switch during the first switching period and for a duration selected based on a signal indicative of negative current from a prior switching period, and the activating the secondary switch results in a positive current through the secondary winding followed by a negative current through the secondary winding; and discharging capacitance of the primary switch by a negative current in the primary winding responsive to the negative current in the secondary winding.
