摘要
等效小参量法是一种改进的扰动技术,适于求取强非线性系统的周期解.最近已成功地将它应用于开关变换器的稳态分析.本文根据该方法的基本思想和求解程序,提出适于瞬态分析的等效小参量法,并用它分析PWM开关变换器的瞬态过程.本文方法计算量小,精度较高.
An improved perturbation technique (equivalent small parameter method) proposed in a recent paper (Int. J. Electronics, 1989, 67(3): 403-414) has been successfully applied to steady-state analysis of DC-DC PWM switching converters. This paper extends the algorithm to transient analysis of a broader class of non-linear systems. As an example, the transient respoase of a PWM switching converter is analyzed to demonstrate its simplicity and accuracy.
