1. A method for operating an active-clamp flyback (ACF) converter, the method comprising:
generating a forward current through a primary winding of a transformer for a first duration;
generating a reverse current opposite the forward current through the primary winding for a second duration at an ending of the first duration, wherein an ending of the second duration corresponds to detecting an overcurrent condition at the reverse current or elapsing of a set time duration; and
stopping the generating of the reverse current for a third duration in response to not detecting an overcurrent condition at the reverse current, the third duration being equal to the set time duration and being after the second duration.
