摘要: 提出了一种适用于三相有源电力滤波器的不对称拓扑,该拓扑结构将无源滤波器与低功率有源滤波器结合以降低电压型逆变器(Voltage Source Inverter,VSI) 的容量,减少系统损耗。该拓扑包含一个三相桥、两相双谐振LC无源滤波器和一相耦合电感。所设计的拓扑方案通过减少器件数量,探讨器件参数差异对有源滤波器(Active Power Filter, APF) 补偿效果的影响。并提出了一种基于虚拟电容电压的补偿控制策略,实现对系统的有效控制,仿真和实验表明本文所提出的拓扑和控制策略是可行的。该拓扑及其控制策略方案在减少器件数量的同时,也便于结合传统对称控制策略使用,易于工程实现。
