资料介绍

针对单端反激式开关电源系统工作的稳定性问题。提出了一种单端反激式开关电源反馈回路的补偿设计方法,设计了基于UC3844电流控制方式的反馈回路和零点一极点补偿电路,并进行了仿真实验。仿真结果表明,本文设计的反馈回路和补偿电路在电网波动和负载变化时仍然可以保证整个系统的稳定性。

For the stability of single flyback switch mode power supply, compensating circuit design method was discussed based on UC3844 which is a current model control chip. Zero-pole compensating circuit and the feedback loop of single flyback switching mode power supply were designed based on UC3844 and simulation experiment was done. The simulation results show that, the stability of the system is guaranteed in both power grid volatility and load changes by using the compensating circuit designed in the paper.
