DC-DC CONVERSION DEVICE HAVING COUPLING INDUCTOR

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...

Zusammenfassung:	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. Selon la présente invention, une inductance de sortie, au lieu d'être composée d'un élément d'inductance séparé, est couplée magnétiquement à une troisième inductance et à une quatrième inductance constituant un second transformateur. Ainsi, par rapport au cas où l'inductance de sortie est composée de l'élément d'inductance séparé indépendamment de la troisième inductance et de la quatrième inductance, le coût ainsi que le volume du dispositif de conversion CC-CC peuvent être réduits. 본 발명에 의하면, 출력 인덕터가 별도의 인덕터 소자로 이루어지는 것이 아니라, 제2 트랜스포머를 구성하는 제3 인덕터 및 상기 제4 인덕터와 서로 자기적으로 결합되어 이루어지는 것이기 때문에, 출력 인덕터가 제3 인덕터 및 제4 인덕터와는 무관하게 별도의 인덕터 소자로 이루어지는 경우에 비해, DC-DC 변환 장치의 가격을 절감할 수 있고 부피 또한 감소시킬 수 있다.
