In this bidirectional insulated DC/DC converter, the pulse width (α or β) of the AC fundamental wave voltage (Va or Vb) corresponding to the higher of two DC voltages (Ea, Eb) is narrowed, causing the root mean square values of the AC fundamental wave voltages (Va and Vb) to match, and then the phase difference (θ) of the AC fundamental wave voltages (Va, Vb) is set in accordance with the value and direction of the desired current. Consequently, even if the difference between two DC voltages (Ea, Eb) is fluctuates greatly, DC power can be stably provided and received. |
