A device including a full bridge, a half bridge, a first inductor, and a second inductor. The full bridge has a first pair of transistors being activated when a load applied to the device is above a predetermined level and deactivated when the load applied to the device is below the predetermined level, and a second pair of transistors being continuously activated. The half bridge has a third pair of transistors that are activated when the load applied to the device is below the predetermined level and deactivated when the load applied to the device is above the predetermined level. The first and second inductors are connected between the outputs of the full and half bridges are adapted to cooperate with each other to provide a zero voltage switching of the device at a light load. The first and third pairs of transistors are activated at different times.
