摘要
文中介绍在变负载情况下,精确检测静态和瞬态电流的方法。通过前端的电阻采样以及后端的信号调理,实现对电流的精确检测。应用INA148对该原理进行实验检验,表明该方法可以对用电设备的电流信息进行精确检测,并在直流载波通讯方面具有实用价值。
A efficiency method of precision checking and measuring for quiescent and transient current is introduced in variable load. By resistance sampling and signal processing precision checking and measuring for current is actualized The design principle is checked by using INA148, indicating the method may be used in current checking and measuring of electro-equipment. At the same time the principle and method can be used in carrier wave communication of direct current practically.
