摘要
详细地论述了1．5MHz高频开关电源变压器设计全过程。该变压器可用于推挽正激等拓扑结构。文章介绍了变压器对高频开关电源的影响,分析了变压器磁芯的特性及变压器的设计方法。
In this paper, in order to design the transformer in 1. 5MHz high frequency switching mode power supply （SMPS） ,the push pull topology is chosen. The influence of the transformers to the performance of SMPS is first pointed out. Then the characteristics of magnetic cores and the design methods of the transformers in SMPS is analyzed.
