Abstract
A power converter includes an input coupled to an inductor, a first switch coupled to a first comparator, and a second switch coupled to a second comparator. The power converter also includes a pulse comparison counter coupled to the first comparator and the second comparator and a synchronous rectifier (SR) calculator coupled to the pulse comparison counter. The synchronous rectifier calculator is operable to modify a conduction time of the first switch during a first AC half-cycle and modify a conduction time of the second switch during a second AC half-cycle.
