Power conversion apparatus and power conversion method

摘要

A power conversion apparatus includes a plurality of power supply circuits each including a primary side circuit, and a secondary side circuit that is magnetically coupled to the primary side circuit via a transformer. Electrical power that changes according to a phase difference between switching of the primary side circuit and switching of the secondary side circuit is input and output to and from the power supply circuit. The power conversion apparatus includes a first power supply circuit, a second power supply circuit that uses, as an input side thereof, an output side of the first power supply circuit, and a control unit that adjusts residual power obtained by subtracting input power of the second power supply circuit from output power of the first power supply circuit, by controlling a phase difference of the first power supply circuit and a phase difference of the second power supply circuit.
