摘要
对采用集成运算放大器组成正序分量和负序分量过滤器的设计进行了深入的研究。目的是使所设计的集成电路型正序分量和负序分量过滤器不仅能精确反映正序分量和负序分量的大小,而且能精确反映正序分量和负序分量的相位,以提高它们的实用性。综合多种集成电路型正序分量和负序分量过滤器的优点并加以改进后设计的集成电路负序分量过滤器,经仿真分析表明只要将该负序分量过滤器的任意两个输入端子互换,即可构成正序分量过滤器,由此而构成的集成电路型正序分量过滤器则能精确反映正序分量的大小和相位。
This paper conducted a research on the design of postitive sequence component and negative sequence component filter composed by integration operational amplifier. The goal is that improve the filter's usabiltiy,precisely reflecting not only the size of positive sequence component and negative sequence component but also the phase. A kind of integrated circuit negative sequence component filter is designed, The simulation analysis indicated the goal is achieved. The positive sequence component constituted by exchanging two input terminals of negative sequence component filter is able to reflect the size and phase precisely.
