平面變壓器在開關電源中應用的優越性分析

摘要：與傳統變壓器相比較，平面變壓器有許多明顯的優勢。它在提高開關電源的功率密度，減小開關電源中磁性元件的體積方面有著重要的意義。因此，近年來平面變壓器被人們廣泛地研究。本文分析綜述了平面變壓器在開關電源中應用的技術優越性。 敘詞：開關電源；平面變壓器；功率密度；交叉繞組； Abstract：Planar transformer provides distinct advantages over the traditional transformer. It plays an important role in the technological evolution towards increased power density of power supplies,reducing the volume of magnetic component is of great significance．So,planar magnetic technology has been the subject of intensive research in recent years．In this paper, compared with the traditional transformer,the advantages of the planar transformer are analysed and reviewed． Keyword：Power supply；Planar transformer；Power density; Interleaving Winding;
