Abstract
In one embodiment, a power apparatus includes a buck converter including a first capacitor, a first inductor and a first switch for connection with a direct current power supply, wherein when the first switch is closed and the buck converter is connected to the direct current power supply, the first capacitor and the first inductor are connected in series to the direct current power supply, a full-bridge inverter including at least four switches including the first switch, a second, third and fourth switch so that the first switch is shared by the inventor and buck converter, the inverter being operative to convert direct current to alternating current by alternating (a) closing the first and fourth switch with the second and third switch open, and (b) closing the second and third switch with the first and fourth switch open, and a transformer to step down an output of the inverter.
