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。

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
