PROBLEM TO BE SOLVED: To provide a power conversion device capable of suppressing lowering of power conversion efficiency between a primary circuit and a secondary circuit.SOLUTION: A power conversion device has a plurality of power circuits having a primary circuit and a secondary circuit which is magnetically coupled with the primary circuit using a transformer. In the power circuit, power is input/output which is changed in accordance with phase differences between switching of the primary circuit and switching of the secondary circuit. The power conversion device also has a control section for adjusting residual power obtained by subtracting input power of a second power circuit from output power of a first power circuit by controlling the first power circuit, the second power circuit using an output side of the first power circuit as an input side, and the phase difference of the first power circuit and the phase difference of the second power circuit. |
