PROBLEM TO BE SOLVED: To achieve the transformer wiring structure of a DC-DC converter in which the leakage inductance of the output wiring pattern of a main transformer is reduced without lowering the efficiency.SOLUTION: In a DC-DC converter where the main transformer output is subjected to board wiring patterning, a floating ground plate is arranged in close proximity to a board where the main transformer output is patterned, so as to reduce the leakage inductance thereof. The floating ground plate is superposed on at least a part of the wiring pattern of a pair of main transformer outputs in the same plane across both wiring patterns. |
