DC-DC DC-DC CONVERTING APPARATUS WITH COUPLED INDUCTOR

摘要

According to the present invention, since the output inductor is not formed of a separate inductor element, but is magnetically coupled to the third inductor and the fourth inductor constituting the second transformer, the output inductor includes the third inductor and the third inductor. Compared to the case in which a separate inductor element is used regardless of the 4 inductor, the price of the DC-DC converter can be reduced and the volume can also be reduced.
