汽车电源启动系统中电流传感器的应用研究

Study of Current Sensor in the Power Supply System of Car

本文介绍了基于霍尔原理的电流传感器,它可监测汽车电源系统的过电流,检测各电动机的驱动电流,通过检测汽车发电机放电电流大小并与实际负荷电流进行比对,可判定是否存在有损汽车性能的故障,并重点论述了如何实现基于霍尔感应原理的传感器的测量,实现了电流传感器在汽车发电系统中的应用,详细解释初级/次级线圈的匝数对感应电流的影响,以及感应电流的输出形式等。

This paper mainly introduces the current sensor based on the principle of Hall, which can monitor the over current of the power supply system of the car and detect the drive current of the motors. By detecting the driving current of the motor, and comparing with the alternator discharge current size, all of the breakdowns can be detected by the Steam current sensor based on the principle of Hall.
