| 摘 要： | 基于级联H桥多电平拓扑的有源电力滤波器(Active Power Filter, APF)的研究越来越广泛。本文针对级联型APF系统的动态性能进行了研究。首先分析了电网电流反馈控制动态响应慢的原因和理想情况时的动态响应，在此基础上提出了一种提高系统动态性能的方法，该方法的特点是:稳态时，系统的控制策略为电网电流反馈控制，负载突变时，系统采用复合控制策略。文中进一步详细阐述了其实现方法，并对级联APF直流侧电容电压均衡控制的原理及其硬件实现进行了描述。仿真和实验结果表明，采用该方法的级联APF具有较高的稳态和动态补偿性能。 |

| Abstract: | The research on the cascade H-bridge multilevel topology based active power filter (APF) is more and more extensive. The dynamic performance and its enhancement of the cascade APF are studied in this paper. The reason why APF with source current feedback control has a poor dynamic performance is analyzed. Based on the discussion of the ideal dynamic response, a method for improving the dynamic performance is proposed. The method has the following features:when steady-state, control strategy of APF is source current feedback control; while transient-state, the control strategy is a kind of composite control. The implementation of the proposed method is presented. The scheme of DC-link voltage balance control is also described. Furthermore, simulation and experiment results show the high performance of the proposed cascade APF. |
