摘要
本文讨论了dq变换谐波计算的高精度要求及低通滤波器的关键作用。通过分析对比多种类型滤波器,认为三阶切比雪夫(Chebyshev)型低通滤波器在性能和实现上综合较优。同时给出了仿真和实验结果。
The high-resolution requirement and the key role of low-pass-filter in d-q transformation are discussed in the paper. By analyzing and comparing several kinds of filter, it is found that a third order Chebyshev low-pass-filter has more advantages to others in its characteristic and implementation. The results of simulation and experiment are also presented in the paper.
