電子變壓器的技術發展趨勢

摘要：為適應電子設備的小型化，電子變壓器的一個主要發展方向，是從立體結構向平面結構、片式結構、薄膜結構發展，從而形成一代又一代的新型電子變壓器：平面變壓器、片式變壓器、薄膜變壓器。文章綜述了R型變壓器、印刷電路（PCB）型平面變壓器、壓電變壓器、薄膜PCB平面變壓器的原理、結構、性能和應用。 敘詞：電子變壓器，技術發展，趨勢，R型變壓器，平面變壓器，壓電變壓器，薄膜變壓器 Abstract：To adapt to the miniaturization of electronic equipment, a major trend for electronic transformer is to develop from cubic structure to flat structure, slice structure and thin-film structure, resulting in a new-generation electronic transformers, namely, flat transformer, slice transformer and thin-film transformer. The paper reviews over principles, structures, performances and applications of R-type transformer, PCT flat transformer, piezo-electric transformer and thin-film PCB flat transformer.
