Abstract: A DAB converter that is capable of inhibiting a decrease in the transmission efficiency of electric power due to an individual difference of the inductance. A DAB converter including: a transformer having a primary-side winding and a secondary-side winding; a first and second full bridge circuit; a first and second capacitor; and a control unit, in which, the primary and secondary side winding is connected between a midpoint and a midpoint of the first full bridge circuit, the first capacitor is connected between two input/output terminals included in the first full bridge circuit, the second capacitor is connected between two input/output terminals included in the second full bridge circuit, and the control unit configured to adjust a phase difference between the switching of the first and second full bridge circuit based on an estimated value of an inductance of the DAB converter.
