| 摘 要： | 反激式开关电源因成本低、外围元器件少、可宽电压范围输入能耗小、支持多组输出而备受欢迎，但因输出电压纹波大而严重影响其工作性能。从反激式开关电源的工作原理出发，采用反激式开关电源输出端增加输出滤波电路的方法，解决反激式开关电源输出电压纹波大的问题。运用Saber仿真软件分别对普通反激式开关电源和增加 输出滤波电路的反激式开关电源进行建模和仿真。试验仿真对比表明，通过该方法可改善反激式开关电源的输出电压纹波，提高了反激式开关电源的工作性能。

| Abstract: | Due to the low cost, less peripheral components, wide voltage range input, low energy consumption, and support for multiple outputs, the flyback power switch is very popular, but the output voltage ripple seriously affects its performance. We add an LC filter circuit in the output thus obtaining a small output voltage ripple and good performance. Simulation results show that the output increase of LC filter circuit is effectively improved by our method. |
