Abstract: A method of compensating for reverse current leakage in an active rectifier may include advancing an output of a comparator by a predetermined period of time by applying a predetermined offset voltage to a reference voltage input to the comparator, and activating a switch based on the output of the comparator. The method may also include deactivating the switch when a predetermined time delay elapses from a point in time at which the switch was activated.
