Application of 20kA Close-loop Hall Current Sensor for Power System in A Nuclear Fusion Equipment

本文介绍闭环霍尔电流传感器的工作原理及在核聚变装置系统中的应用,实现了对核聚变装置供电系统中直流大电流的隔离测量、控制,解决了该装置能量的稳定供给问题。

This article presents a principle of a close-loop Hall current sensor and an application of the sensor for a power system in a nuclear fusion equipment. The sensor is used to measure an output current of the power system and the output signal of the sensor is isolated between the primary current （The output current of the power system） and the secondary current （The output signal of the sensor）. According to this application,we solve a problem to protect the high power system in a nuclear fusion equipment by limiting the output current of the system.
