Abstract
A power conversion apparatus includes a transformer comprising a primary coil and a secondary coil; a primary full-bridge circuit comprising the primary coil disposed at a first bridge part; a secondary full-bridge circuit comprising the secondary coil disposed at a second bridge part; and a control unit configured to control a phase difference between switching at the primary full-bridge circuit, and switching at the secondary full-bridge circuit, to adjust transmission power transmitted between the primary full-bridge circuit and the secondary full-bridge circuit. When an absolute value of the phase difference is less than or equal to a first predetermined value, the control unit inverts a positive and a negative of the phase difference, to switch a power transmission direction between the primary full-bridge circuit and the secondary full-bridge circuit.
