摘要
基于等效小参量法所得的稳态周期解，本文将特征方程分析法推广应用于开关功率变换器闭环系统平衡点稳定性分析当中。文中着重阐述了其基本原理。分析实例表明，结合相轨迹曲线，此方法简单而直观，具有明显的实用价值。
A characteristic extension equation analysis method (CEAM) for the stability analysis of equilibrium points for closed-loop PWM power switching converters is introduced based on equivalent small parameter (ESP) method .The basic principle is described in detail. The provided example shows that this method, incorporating with the system's state-plane trajectories , offers the advantages of both simplicity and practicality.
