Patent ID: 7529110

Claim:
A power conversion device for receiving AC and/or DC power and providing a DC output, the device comprising: an AC input; a DC input; an output; AC-to-DC converter circuitry coupled to the AC input and to the output and configured to convert an AC voltage received at the AC input into a first output DC voltage and to provide the first output DC voltage to the output; non-isolated DC-to-DC up/down converter circuitry coupled to the DC input and to the output and configured to directly convert an input DC voltage received at the DC input into a second output DC voltage that is one of a down-converted DC voltage that is lower than the input DC voltage and an up-converted DC voltage that is higher than the input DC voltage, the DC-to-DC up/down converter circuitry being further configured to provide the second output DC voltage to the output; an auxiliary output; and non-isolated DC-to-DC down converter circuitry coupled to the auxiliary output, to the DC-to-DC up/down converter circuitry, and to the AC-to-DC converter circuitry and configured to convert a DC voltage provided by the DC-to-DC up/down converter circuitry and/or by the AC-to-DC converter circuitry to a lower voltage level and to provide the lower voltage level to the auxiliary output.
