摘要
基于小信号传递函数的网络分析理论,对60 W反激电源进行反馈补偿网络设计.为使补偿后电源系统达到较好的系统动态响应、负载调整率及更好的稳定性,补偿前对各网络进行分析,得出各网络的传递函数.按照补偿后系统伯德图应满足的3个特性,对电压反馈补偿网络进行设计.使用Matlab软件提供的伯德图分析工具对反馈网络传递函数进行分析,优化得到最佳参数.最后验证了该补偿网络可以使电源达到较好的静态与动态响应.
This paper designs 60W flyback power supply compensation network based on the network analysis theory of small-signal transfer function.In order to make the power supply system to achieve the best dynamic response,load regulation and stability,the network before compensation is analyzed and obtains each network transfer function.According to the three characteristics which the compensation system Bode diagram need to have,this paper designs the feedback compensation network.In this process,the Bode tools in Matlab are used to get the best parameters.Finally,this compensation network allows the power supply to achieve good static and dynamic response.
