Abstract
A bidirectional insulated DC/DC converter narrows a pulse width of an AC fundamental wave voltage corresponding to a higher DC voltage of two DC voltages, to cause effective values of the AC fundamental wave voltages to coincide with each other, and then, sets a phase difference between the AC fundamental wave voltages 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 greatly varies, DC power can be stably transmitted and received.
