摘　　要：基于霍尔元件和霍尔传感器的原理与特点,以集成霍尔传感器UGN—3501M为例,论述了将其应用于直流电流自动检测的方法,并通过实验验证了该方法。实验结果表明,将霍尔传感器用于直流电流的检测,检测电路不会影响直流回路,只要正确使用霍尔传感器技术参数,并采用对温度、不等位电势的补偿以及线性化处理技术,即可获得良好的检测性能。Based on the principle and characteristics of Hall parts and Hall sensors,this paper takes the integrated Hall sensor UGN —3501M as the example,elaborates the method for the direct current automatic detection using it,and has confirmed this method through the experiment.The experimental result indicates that the detecting electric circuit is not to be able to affect the direct current return route,and a good detecting performance would be gained if the technology parameters of the Hall sensor are used correctly and if the technologies of compensating for temperature and non-equipotential electric potential as well as linearized processing technologies are used.
