A first high side switch and a first low side switch may be coupled in series along a first path of a full bridge circuit, having a first node between the first high side switch and the first low side switch. The power converter may also comprise a second high side switch and a second low side switch coupled in series along a second path of the full bridge circuit, having a second node between the second high side switch and the second low side switch. The power converter may further comprise a first path capable of providing a first rectifier drive signal from the first node to a second rectifier switch, and a second path capable of providing a second rectifier drive signal from the second node to a first rectifier switch.
