A DC-DC converter includes a first switching network that receives an input DC voltage and outputs a first AC voltage, a transformer, and a secondary side conversion circuit. The first switching network receives an input DC voltage. The transformer includes a middle-point primary tap such that when the input DC voltage is in a low voltage range, the middle-point tap of the transformer primary is connected to the input DC voltage causing current to flow through the first plurality of primary windings in parallel to current flowing through the second plurality of primary windings and when the input DC voltage is in a high voltage range, the middle-point tap is disconnected from the input DC voltage causing current to flow through the first plurality of primary windings in series with current flowing through the second plurality of primary windings.
