A bidirectional or unidirectional DC-DC converter includes a primary stage and a secondary stage. The primary stage is configured to receive or output a first DC voltage. The primary stage includes a first switching network configured to convert the first DC voltage to a first alternating current (AC) voltage or vice versa. The DC-DC converter also includes a transformer having primary windings and secondary windings. The primary windings are in electrical communication with the first switching network. The transformer is configured to convert between the first AC voltage and a second AC voltage. The DC-DC converter also includes a secondary stage that has a second switching network. Characteristically, the second switching network and the transformer operate as an interleaved converter to convert the second AC voltage to an output DC voltage or vice versa. Advantageously, the required series inductance for this interleaved converter is integrated into the transformer.
