Patent ID: 6995987

Claim:
A DC-DC power converter, comprising: first and second input terminals; at least one electrical element connected to at least one of the first and second input terminals, the at least one electrical element being operative, in the event a first voltage is applied across the first and second input terminals, to provide a second voltage having a value between the first voltage value and a reference voltage value; at least one transformer having at least one primary winding and at least one secondary winding; a switch assembly including a plurality of switching elements, the switch assembly being operatively connected to the first input terminal, the second input terminal, the electrical element, and the transformer primary winding, wherein the switch assembly is operative, in the event the first voltage is applied across the first and second input terminals, to switchably apply the first voltage, the second voltage, and the reference voltage, across the transformer primary winding to generate at least one third voltage across the transformer secondary winding; a plurality of output terminals; and a rectifier connected between the transformer secondary winding and the output terminals.
