    摘要: A bidirectional insulated DC/DC converter narrows a pulse width (± or ²) of an AC fundamental wave voltage (Va or Vb) corresponding to a higher DC voltage of two DC voltages (Ea, Eb), to cause effective values of the AC fundamental wave voltages (Va and Vb) to coincide with each other, and then, sets a phase difference (¸) between the AC fundamental wave voltages (Va, Vb) in accordance with a value and a direction of a current that is desired to flow. Accordingly, even when the difference between the two DC voltages (Ea, Eb) greatly varies, DC power can be stably transmitted and received.
