PCB型罗戈夫斯基线圈电流传感器设计

Design of Current Sensor Based on PCB Rogowski Coils

介绍了罗戈夫斯基线圈的基本原理.对比普通罗戈夫斯基线圈传感器,设计了基于印刷线路板（PCB）型罗戈夫斯基线圈的电流传感器,其工作频带为0～1 MHz,测量电流最大可达100 A,测量精度为0.1 A.该传感器具有结构简单,抗干扰能力强等优点.

The principle of Rogowski coil is introduced first,and it is compared with the ordinary Rogowska coil sensor; then a current sensor based on PCB rogowski coils is designed. Its working frequency band is 0 ～ 1 MHz,and the maximum current is 100 A,and its measurement accuracy is 0. 1 A. The sensor has the advantages of simple structure,strong anti-interference ability.
