摘要
基于安培环路定理和霍尔效应,设计制作了一种电流测量装置.该装置利用线性霍尔元件,提供了一种间接测量电流的方法,并对0～20A的直流电流进行了实验验证.实验结果表明：该装置的测量精度满足测量要求.
Based on the Ampere loop theorem and the hall effect, a current measurement de- vice was designed and manufactured. Using the linear Hall element, this device provided a method of indirect measurement of current. Experimental verification for a DC current from 0 to 20 A was carried out. The experimental results showed that the measuring accuracy of this device met the measurement requirements.
