基于非线性电感模型的稳压变压器的建模研究

论文通过对稳压变压器的基本结构和工作原理的分析提取出饱和电抗器作为稳压变压器的一个元件。饱和电抗器经非线性化处理后引入稳压变压器的等效电路中。用MATLAB对实验数据进行拟合得出饱和电抗器的模型,以此为基础对稳压变压器模型进行仿真分析,同时得出模型的输出信号的频谱。仿真结果证明了仿真模型高度接近实物。

Construction and Study of Constant Voltage Transformer Based on Nonlinear Inductance Model

Through analyzing the basic structure and working principle of constant voltage transformer, this paper extracts saturation reactor as an element of constant voltage transformer. After operating nonlinearly, saturation reactor is drawn into the equivalent circuit of constant voltage transformer. The model of saturation reactor comes from fitting to prototyping testing data by MATLAB. The model of constant voltage transformer is analyzed through simulating based on the model of saturation reactor, and at the same time the frequency spectrum of constant voltage transformer＇s model comes out. The simulation result proves that the simulation model is close to the real object.
