A system and method of synchronous rectification includes a synchronous rectifier circuit. The synchronous rectifier circuit includes a direct current (DC) load coupled between a DC output node and a ground node, an alternating current (AC) source applying an AC waveform to an AC input node, an upper switch coupled between the DC output node and the AC input node, and a lower switch coupled between the AC input node and the ground node. In a first state, the upper switch is turned on and the lower switch is turned off. In a second state, the upper switch is turned off and the lower switch is turned on. In a third state, the lower switch is operated in an enhanced detection mode. The synchronous rectifier circuit transitions from the second state to the third state when the voltage of the AC input node increases above a threshold voltage.
