摘要
针对单周控制APF的控制要求和特点,详细给出了输出电感值、直流电容值、积分时间常数、PI调节器等几个关键参数最优选择分析,并以三相APF为例建立了仿真和实验模型,给出了最优化设计后的仿真和实验结果。结果表明经过参数优化设计后,APF补偿性能得到很大改善,补偿后总谐波失真度小,系统稳定性好,验证了参数最优设计分析的正确性和有效性。
In this paper, aiming at control requirement and characteristic of one-cycle controlled APF, optimal selection of several important parameters including output inductance, DC capacitance, integration time constant and PI regulator are analyzed in detail, and the model of a three-phase three-wire APF is built, its simulation and experimental results after parameters optimal design are given, the results show that compensation performances of APF are greatly improved, low total harmonic distortion and good system stability are obtained, and verify the correctness and validity of parameters optimal design analysis.
