传统上，单相功率因数校正器的响应时间较慢，其特征在于低电压环路带宽（<1Hz），这是确保输入电流中的适当THD所必需的。本文探讨了实际的离散滤波器，以大大提高电压反馈环路带宽。分析的结果表明，移动平均滤波器的形式是一种有效的解决方案。分析表明，这是一个很好的实用滤波器PFC控制，需要低的计算开销和基本的离散信号理论素养的实现。经常被忽视的，实用的理论/方法，简单的实施是最重要的标准，实践工程师。仿真和实验结果证实了该技术的优势，并验证了本文的理论分析。
Traditionally, single-phase power factor correctors suffer from a slow response time, characterized by a low voltage loop bandwidth (<; 1Hz) that is necessary to ensure a suitable THD in the input current. This paper examines practical discrete filters to substantially improve the voltage feedback loop bandwidth. As a result of the analysis, the form of a Moving Averaging Filter proves to be an effective solution. The analysis shows that it is an excellent practical filter for PFC control that requires low computational overhead and basic discrete signal theory literacy for its implementation. Often ignored, useful theory/methods with simple implementation are the most important criterion for practicing engineers. Simulation and experimental results confirm the advantages of the technique and validates the theoretical analysis presented in the paper.
