LIU Xiao-yuan, XU Liu-wei, JIANG Jia-fu, et al. Study and application of 25kA Hall sensor in EAST toroidal power supply[J]. 2010, 29(11): 138-140. DOI: 10.13873/j.1000-97872010.11.044.
On the basis of the detailed analysis on the magnetic circuit of the Hall current sensor
the DC transfer function of current sensor was deduced.The correctness of the theoretical calculations is verified by 3-D electromagnetic field simulation and calculations through the electromagnetic simulation software ANSYS.Main parameters of the 25 kA Hall current sensor and its application in EAST toroidal field power supply was introduced.
