Claim:
1. An isolated buck converter operable to receive a direct current (DC) voltage from a power source and provide a substantially DC output voltage to a load, said isolated buck converter comprising: a high switch connected to the power source; a low switch connected to the high switch and a ground of the power source, the connection between the high switch and the low switch forming a first junction; a high bulk capacitor connected to the power source; a low bulk capacitor connected to the high bulk capacitor and to the ground of the power source, the connection between the high bulk capacitor and the low bulk capacitor forming a second junction; an isolating transformer having a primary winding and a secondary winding, wherein the primary winding is connected between the first junction and the second junction; a rectifier connected to the secondary winding of the isolating transformer; an output inductor connected to an output of the rectifier, wherein the output inductor is configured to provide the DC output voltage to the load; and a switch controller connected to the high switch and to the low switch, wherein said switch controller is configured to
