摘要
为了消除变频器输出波形中谐波分量对变频调速系统的影响,提高变频调速系统性能,本文提出一种三相变频器输出滤波器的工程设计方法,给出滤波器的结构选择依据和滤波器参数的计算方法,并进行了系统仿真和实验验证,实验结果表明该三相滤波器设计方法可行、有效。
In order to eliminate the influence of the harmonic components in the output waveform of the frequency converter and improve the performance of the variable frequency speed regulation system, a design method for the output filter for the three-phase inverter is proposed in this paper.The selection of filter structure and the calculation method of filter parameters are also carried out.Finally, the design results are simulated and verified by experiments.Experimental results show that the three-phase filter design method is feasible and effective.
