Abstract
Focus on the problems of current sensor model based on MATLAB/Simulink/Simscape, such as the internal structure of the model is simple and not reflect the principle and structure itself, the measurement results is ideal and not reflect the influence of noises. Therefore, a model is designed, which can reflect the principle, internal mechanism and the measurement error of hall current sensor in the simscape modeling environment. The model reflects the closed-loop principle, includes the current noise and other interference factors, and the model has no load effect on the measuring circuit. Test results show that the model system can better reflect the actual phenomenon, and make a prominent contribution for the research of circuit.
