资料介绍

在开关电源设计中,反馈环路的计算以及补偿一直是影响其性能的重点与难点,其能减少静态误差、提高系统动态响应与减少负载调整率。通过对Boost电源的小信号模型的分析,根据系统特性,进行了补偿网络的设计,然后用SABER软件对设计方案进行仿真验证,最后利用PWM芯片SG3525搭建一Boost电路,对其动态响应以及稳定性进行验证。

During the design of switching power supply,the calculation and compensation of the feedback loop are the important and difficult point affecting the performance. It can reduce the static error and load regulation and improve the dynamic response of system. Through the small signal model analysis of Boost converter,a compensation network was designed based on system features, and then SABER software was used for simulating the design. A Boost converter was made by SG3525 to verify its dynamic response and stability.
