| 摘 要： | 基于数字控制芯片si8250研制了2660W单相功率因数校正(Power Factor Correction,简称PFC)控制器.提出了采用滑模变结构电流内环与由PI调节器和数字低通滤波器组成的电压外环相结合的控制系统,以实现高性能高速度的功率因数校正.实验结果表明,该变换器能在90～264 V的输入范围内得到420V的稳定直流电压,且具有功率因数高,输出电压纹波小,系统稳定性好等优点.

| Abstract: | This paper proposes a 2660W Boost Power Factor Corrector(PFC) based on si8250 digital controller of the Silicon Labs company.This PFC was realized by employing sliding-mode variable-structure inner current loop control and outer voltage loop PI control with digital low-pass filter to achieve high performance.The experimental results proved that this PFC can get steady 420V output voltage when input voltage range from 90V to 264V.It also has good dynamic charac-teristics and strong robustness. |
