摘要
介绍了一款反激磁隔离开关电源的环路补偿设计方法.首先建立反激磁隔离开关电源的小信号传递函数,然后对反馈环路的设计参数进行定性分析和定量计算,并设计合适的相位裕量和增益裕量.最后,搭建仿真分析模型和试验验证电路.结果证明提出的设计方法是可行的,具有较好的通用性.
Abstract
A loop compensation design method of a flyback magnetic insulation switch power supply is introduced.Firstly,the small signal trausfer function of the flyback magntic insulation switch power supply was established.Then,the design parameters of the feed back loop were qualitatively analyzed and quantitatively calculated.The appropriate phase margin and gain magin were designed.Finally,a simulation analysis model was built and the experimental verification circuit was conducted.The results prove that the adapted design method is feasible and has good universality.
