Abstract
Phase differences between primary-side series-connected first and second arms and secondary-side series-connected fifth and sixth arms and between primary-side series-connected third and fourth arms and secondary-side series-connected seventh and eighth arms are controlled for power being transmitted from the secondary side to the primary side. Turn-off of the fifth arm is corrected to cause an integrating result of a secondary coil current for an interval delayed by a current sensor response delay from an interval between turn-off of the first arm and turn-on of the seventh arm to approach zero, or turn-off of the seventh arm is corrected to cause an integrating result of the secondary coil current for an interval delayed by the response delay from an interval between turn-off of the third arm and turn-on of the fifth arm to approach zero.
