一种改进的有源电力滤波器的应用研究

Application Research on An Improved Active Power Filter

介绍了有源电力滤波器APF的基本工作原理、谐波和无功电流检测方法以及电路中补偿电流控制方法。在此基础上提出了一种改进设计,并通过MATLAB/Simulink对并联电压型APF进行仿真研究。结果表明,三角波比较控制的APF能对谐波电流和无功进行较好的补偿。

In this the compensation was simulated by the harmonic and paper, the basic principle of active power filter （APF）, the methods of harmonic and reactive current current control in circuit were introduced, and an improved method was proposed. The whole shunt detection and APF system MATLAB/Simulink. The results show that APF controlled by triangle pulse comparison method can compensate reactive current quickly.
