摘　　要：与传统变压器相比较,平面变压器有许多明显的优势。它在提高开关电源的功率密度、减小开关电源中磁性元件的体积方面有着重要的意义。因此,近年来平面变压器被人们广泛地研究。本文分析了平面变压器在开关电源中应用的技术优越性。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.
