Claim 8:
9. The DC/DC converter according to claim 8, wherein
the control circuit sets, as a third phase shift amount, a phase shift amount of an on/off drive signal of the second diagonal element with respect to an on; off drive signal of a second reference element that is the switching element on one of the positive electrode side and the negative electrode side of the third bridge circuit,
the control circuit sets, as a fourth phase shift amount, a phase shift amount of an on off drive signal of the first diagonal element with respect to an on/off drive signal of the second reference element, and
in the second power transmission,
in a range in which the second power transmission amount is smaller than the second reference value, the control circuit decreases the third phase shift amount and the fourth phase shift amount from a maximum value when the second power transmission amount is zero, in accordance with increase of the second power transmission amount, and
in a range in which the second power transmission amount is equal to or greater than the second reference value, the control circuit decreases the third phase shift amount and increases the fourth phase shift amount from the third phase shift amount and the fourth phase shift amount when the second power transmission amount is the second reference value, in accordance with increase of the second power transmission amount.
