摘要
为了研究磁损耗分离技术，首先研制了用于磁损耗分离技术的多频功率电源．根据磁滞损耗和涡流损耗与频率的关系，实现了对贴近工程实际的模型－ＴＥＡＭ２１基准问题的磁损耗分离，并将实验结果和计算结果进行了比较．为国内外磁损耗算法的研究者进一步提供了实验数据。
In order to analyze the relative importance of each part loss (hysteresis loss and eddy currentloss) in magnetic losses, and so that some measurements can be taken to low the losses, it has important sig-nificance to study the separation techniques for magnetic losses. The study of testing method is done in thispaper. First a power source which can supply many different frequencies was made by us. Its feature are largeexciting current supplied, near frequencies and by capacity conpensation, the circuit working in the resonantstate. According to the relation of hysteresis loss and eddy current loss with excitation frequency, we separatedhysteresis loss and eddy current loss from total magnetic losses in the Model B of TEAM Benchmark Problem21
