摘要

双曲Takács模型已被广泛接受并用于磁性材料的磁滞回线表示。为了提高软磁材料的精度，本文将原有的Takács模型扩展为包含高斯函数的模型。在Matlab/Simulink环境下，将修正后的磁滞模型纳入单相变压器模型。通过比较测量和计算得到的输入电流响应，验证了修正Takács模型的准确性。结果表明，1kVA 220/110V变压器的实测电流波形与模拟电流波形吻合良好。

An extension of Takács model for hysteresis loop representation of single-phase transformer

Hyperbolic Takács model has been accepted and widely used for hysteresis loop representation of magnetic materials. In this paper, the original Takács model is extended to include Gaussian function for accuracy improvement of soft magnetic material. The modified hysteresis model is then incorporated into single-phase transformer model in the Matlab/Simulink environment. An accuracy of the modified Takács model is verified by comparing input current responses obtained from measurement and computation. The results show good agreements of the measured and simulated current waveforms of 1kVA 220/110V transformer.
