摘要
就V/F方式在交流采样中的特点进行了讨论,对这种模数变换方式用于工频交流采样时由于积分效应引起的变换误差或时间滞后进行了分析,提出了一种确定统一时滞的校正方法,并已用于数据采集系统中.
The fundamental principle and characteristics of V/F converter using in AC sampling is analyzed. As integral effect of the converter, some time delay will be accompanied. Consequently, some conversion error occurs. The error mechanics is analyzed and the effective error correcting method which is practically applied in data acquisition systems, is described.
