高频平板变压器的原理与设计 高频平板变压器的原理与设计[注] 新加坡南洋理工大学叶虹 西安交通大学叶治政 (南洋道639798)(西安710049) 摘要：运行在高频的常规变换变压器存在着漏电感大，匝间电容量大，趋肤效应、邻近 效应严重，磁芯有局部过热点等问题。一种新型变压器，高频平板变压器已开发出来， 它能减小漏电感和匝间电容，能消除常规变压器存在的磁芯局部过热点，能使趋肤效应 、邻近效应等问题得以改善，它具有很高的功率密度、很高的效率、很低的电磁干扰和 简易价廉等优点。 关键词：平板变压器原边电感漏感趋肤效应邻近效应 Principle and Design of High Frequency Flat Transformer Abstract:While operating in high frequency, conventional transformers have many problems such as large leakage inductance and great inter winding capacitance, skin and proximity effects and the single hot spot at the center of the core. A new type transformer, high frequency flat transformer, has been developed. This kind of transformers can eliminate the single hot spot effectively ……
