摘要
对开关电源的补偿网络设计一般有频域模型计算法、时域试探法及以上方法的综合。由于计算模型和经验值的不准确性，往往需要较长的时间反复调试补偿网络才能得到理想的动态性能和稳定性。文中采用的方法首先采用频率响应分析仪测量系统的实际开环频率特性波特图，然后用K-fact法精确计算补偿器的元件参数，大大缩短了设计时间而且有比较好的调节精度，并用一个反激式电源设计实例进行了设计方法说明。
This paper introduce a method that to find. An approach method of fast establish feedback loop compensation is introduced, which is finding out the open loop characteristics of SMPS by frequency response analyzer, then calculate which is fast and accurate. A design example the value of the network components by K-fact of a fly-back convertor is represented also.
