摘要
针对谐波抑制和无功补偿的问题,对有源电力滤波器进行一系列研究,阐述了有源电力滤波器的基本原理以及控制策略。基于TMS320LF2812设计了有源电力滤波器,包括DSP控制板、电压采样电路,电流采样电路以及IPM功率单元的设计,并给出了有源电力滤波器的软件设计。最后利用MATLAB仿真软件对所涉及的有源电力滤波器进行仿真,验证了有源滤波器系统的正确性以及谐波补偿电流和滞环比较控制模块的有效性。
To aim at harmonic suppression and reactive power compensation problem,this article carry on a series of research of active power filter to expound the basic principle an control strategy.The Parallel Active Power Filter（APF）and its software have been designed based on TMS320LF2812 and its software,including DSP control plates,voltage sampling circuits,current sensing circuits and IPM Power units,and implement some simulations and analysis based on MATLAB to verify the correctness of the filter system,and the effectiveness of harmonic compensation current and hysteresis comparison control module.
