Abstract
A power conversion device for receiving AC and/or DC power and providing a DC output includes: 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; and 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.
