CPLD在多功能谐波分析仪设计中的应用

The Application of CPLD in Design of Multi-function Harmonic Analyzer

鉴于传统的电力谐波分析仪的缺点,文章提出了一种基于可编程逻辑器件(CPLD)的改进方案,能大大地提高谐波分析的精度以及响应速度,同时大大地精简了硬件电路,系统升级非常方便。并给出了主要的设计过程和仿真波形。

Owing to the defects of traditional harmonic analyzer, the paper put forward an effective strategy based on CPLD. The strategy will contribute to improving capability and response. Meanwhile, it will reduce hardware circuit largely and to update system will be easier. The paper also introduced the main process of design and simulation waveform.
