摘要
漏磁变压器,是指通过漏磁支路对主磁通的分流作用,而实现稳压功能的一种特种变压器。文中针对一种微波炉用漏磁变压器,详细地阐述了其利用主磁路的饱和效应及漏磁支路的非饱和特性,实现稳压的工作原理与工作条件,并在此基础上,给出了漏磁变压器的设计原则。基于电磁关系的分析,文中建立了漏磁变压器的等效电路与仿真模型。最后,通过实验验证了等效电路与仿真模型的准确性,对漏磁变压器的设计提供了有效的指导。
The magnetic leakage transformer is a kind of particular transformers which achieves voltage regu- lation function by dividing the main flux with the leakage magnetic branch. Around a basic structure of mag- netic leakage transformer used in microwave oven, the paper elaborated on the regulator principle of the mag- netic leakage transformer and presented its design principles. Meanwhile, the paper presented a widely ap- plicable equivalent circuit of the magnetic flux leakage transformer and built a solving model based on the magnetic circuit method. Simulations and experiments have performed to indicate the regulator performance of magnetic leakage transformer.
