Abstract
A power conversion method of a power conversion device including a primary side port disposed in a primary side circuit and a secondary side port disposed in a secondary side circuit magnetically coupled to the primary side circuit with a transformer, the power conversion device adjusting transmission power transmitted between the primary side circuit and the secondary side circuit by changing a phase difference between switching of the primary side circuit and switching of the secondary side circuit, and changing a voltage of the secondary side port by a DC-DC converter connected to the secondary side port, the power conversion method including: monitoring a voltage ratio of a voltage of the primary side port and the voltage of the secondary side port; and causing the DC-DC converter to operate when the voltage ratio deviates from the reference value by the specified value or more.
