| 摘 要： | 提出了一种测量级联电路稳定裕量的工程实现方法.级联电路系统的稳定裕量由其连接界面的输出输入阻抗比率决定,通过在连接界面上注入外部小信号干扰电流IP,并测量负载侧的响应电流IL的幅值,则可得到该系统的稳定裕量.经理论严格证明的同时,这一方法还得到了实验的验证.

| Abstract: | This paper proposed an engineering approach to examine the stability margin of cascade circuits. The system stability of cascade circuits is determined by the impedance ratio on the cas-cade interface. By injecting small -signal external perturbation current Ip into the cascade interface and measuring the magnitude of the load side response current IL, the system stability margin can be figured out. The proposed approach is strictly developed in theory and demonstrated by experiment. |
