摘要
谐波检测是对谐波问题研究的一个重要组成部分,也是研究分析谐波问题的主要依据和出发点。本文针对谐波检测仪前置通道中的抗混叠滤波器进行分析和设计,采用Sallen-key电路作为滤波主电路,实现了滤波和抗混叠的技术要求,并应用在高性能谐波检测仪实际电路中。
The harmonic detection has been an important part of the harmonic research, as well as the main basis and start point. Anti-aliasing filter in the front end circle channel in the electric network harmonic detection is analyzed with Sallen-key circuit as the main filtering circuit, the filtering and anti-aliasing technical requirements are reached, and the anti-aliasing filter have been applied in high performance harmonic detection instrument circuit.
