k method and apparatus for DC-DC conversion includes a DC-DC converter having two active, three-phase full-bridges (14, 16) in arallel on a primary side (18, 19) of a pair of high-frequency transformers (20, 22). A secondary side (28, 26) of each transformer (20, 22) may be separately connected to one of a pair of series-connected, three-phase diode bridges or serially connected together to a single three-phase diode bridge (30).
