谐波抑制的一个重要趋势是采用有源电力滤波器，有源电力滤波器也是一种电力电子装置，且相关技术的研究也日渐成为研究的热点。本文阐述了几种常见APF的拓扑结构及各自的优缺点，详细分析了基于瞬时无功功率理论的谐波检测方法，比例控制和前馈控制两种电流环控制策略以及SPWM和SVPWM两种调制策略。(the harmonic suppression is an important trend of active power filters, active power filter is a power electronic devices, and related technologies are increasingly become a hot topic. This paper describes the topology and their advantages and disadvantages of several common APF, a detailed analysis of the harmonic detection method based on instantaneous reactive power theory, and proportional control and feedforward control of)
