| 摘 要： | 针对以往开关变换器建模过程中一些理想化假设会引起较大误差的问题,为系统预测的稳定性,以Buck变换器为例,采用状态空间平均法建立在非理想条件下的数学模型,并利用MATLAB软件对模型进行仿真,仿真结果与理想模型和Buck变换器实际电路模型的输出波形进行对比分析,非理想模型的仿真波形和实际电路模型的波形基本一致。结论表明建立的非理想Buck变换器状态空间数学模型具有合理性和可行性,在PWM DC-DC开关变换器的建模分析中考虑寄生参数的实用性更强。

| Abstract: | For some ideal assumptions could bring errors during the modeling of switching converters,this article establishes the mathematical model of unideal buck converter based on state-space averaging method.The model is simulated using MATLAB software.The simulation result is compared with that of the ideal model and the accurate circuit model.The wave-form of the unideal model is nearly accorded with the accurate circuit model's.Conclusion can be drawn that the state-space averaging model of unideal buck conver... |
