摘要
电源反馈环中补偿网络的设计对电源性能有着十分重要的作用。它起到提高系统动态响应,减少负载调整率等作用。文中首先分析了以OB2263为PWM芯片的反激式电源的系统特性,然后提出补偿网络的优化设计方案,最后制作了实验样机进行验证。结果表明,所设计的补偿网络能较大地提高系统的性能。
The compensation network design of the feedback loop is very important to the performance of power su ply. It can improve the dynamic response of the system and reduce the load regulation. This article first analyzes the system feature of the flyback power supply based on OB2263, and then proposes the optimized design of the compensation network. Finally, experiment prototype is made to verify the design. The result shows that the designed compensation network can improve the dynamic response of the system.
