Claim 2:
3. The DC/DC converter according to claim 1, further comprising
a current sensor to detect charge or discharge current of the second DC power source, wherein
the control circuit changes the first phase shift amount and the second phase shift amount such that the charge or discharge current detected by the current sensor approaches a current command value,
in the first power transmission in which the current command value is set so as to charge the second DC power source, when a phase difference between the first phase shift amount and the second phase shift amount is greater than the short-circuit prevention period of the first and second bridge circuits, the control circuit determines that the first power transmission amount is greater than the first reference value, and stops on/off drive of the positive electrode-side switching element and the negative electrode-side switching element in the third bridge circuit, whereas when the phase difference is smaller than the short-circuit prevention period of the first and second bridge circuits, the control circuit determines that the first power transmission amount is smaller than the first reference value, and stops on/off drive of the positive electrode-side switching element and the negative electrode-side switching element in both of the third bridge circuit and the fourth bridge circuit.
