Abstract: According to the present invention, an output inductor, rather than being composed of a separate inductor element, is magnetically coupled to a third inductor and a fourth inductor constituting a second transformer. Thus, compared to the case in which the output inductor is composed of the separate inductor element independently of the third inductor and the fourth inductor, the cost as well as the volume of the DC-DC conversion device can be reduced.
