摘　　要：提出了电力电子电路中变压器的完整集中参数模型,并做了简化,得出中频变压器的等效模型,即时间响应特性等效模型。分析了模型相关参数的计算方法,并给出了在实际电路分析中选用不同模型的原则。试制了样机和实验平台,通过实验证明了变压器时间响应特性等效模型的正确性。In this paper, the lumped full model of the transformer in power electronic circuits is presented, and two simplified methods are given. The models of the intermediate frequencies trans- former are derived, namely the time response characteristics model and the energy transmission char- acteristics model. Analysis of the parameters calculation method of the above models, and the princi- ple of the selection of different models are given in the actual circuit analysis. At last, the prototype and the experimental platform are structured. Experiments have been carried out, and the results demonstrate the correctness of the time response characteristics model of the transformer.
