单端反激电路的建模

Modeling for Single-ended Flyback Circuit

针对现有的五种反激电路的数学模型，结合实验以及仿真的方式，得到适合文中单端反激电路的一种模型。首先，利用Matlab仿真软件分别对五种功率级数学模型进行仿真，得到输出的时域指标；然后，针对一种UC3843控制的单端反激电路，通过实物实验、Psim软件仿真，得到输出的时域指标；最后，通过对比分析，确认符合文中单端反激电路功率级的模型。

According to existing five kinds of mathematical model of the flyback circuit,we get a new single-ended flyback circuit of a model by the experiment and simulation. First of all, time domain parameters and indexes are obtained byMatlab software to the simulation of mathematical model of five power stage. Then, in view of a single-ended flyback with UC3843, we get the output time domain index through the physical experiment and Psim software. Finally, through the contrast analysis, we confirmed that the model conform to the single-ended flyback circuit of the power stage.
