摘要
针对有源电力滤波器(APF)的控制算法复杂且对实时性和精度要求高,而传统的DSP软件方法实现过程中存在着不能并行运算等问题,提出了一种基于可编程逻辑器件(FPGA)的APF控制系统设计方案。阐述了谐波检测方法及改进后的补偿电流控制方法。以FPGA EP1C12Q240C8为控制器搭建了试验平台。试验结果验证了该控制方法及APF控制系统设计的正确性。
Aiming at the features of complexity, real-time and high-accuracy of single-phase active power filter （APF） , and the problems of impossible parallel computation in the traditional DSP software realization, a new control system design method of APF based on FPGA was proposed. The harmonic current detecting method and the improved current compensation control method were dis,cussed. An experimental platform with FPGA EP1C12Q240C8 as the controller was built. The experimental results verify the effectiveness and correctness of the control method and design method of APF control system.
