基于Maxwell与Simplorer仿真分析磁通门磁场传感器瞬态响应
Transient Response Analysis of Fluxgate Magnetometer through Maxwell and Simplorer
摘要
Abstract
In order to get a full knowledge of the operation principle of the fluxgate magnetometer,a magnetic circuit and electric circuit co-simulation model is established through Maxwell and Simplorer.Waveform of the excitation current andtransient response of the fluxgate magnetometer are simulated with this model.Sensitivity of the second harmonic signal and scaling factor of the fluxgate magnetic are calculated with the simulation results.A fluxgate sensor,constructed with Co-Based amorphous ribbons and driven by a switching circuit,is used to validate this model.Waveform of the measured excitation current is the same with the waveform of the simulated current,and error between the sensitivity of the simulated fluxgates and the sensitivity of the real fluxgate is less than 1.1 percent.Scaling factor is got by measuring the frequency response of the fluxgate magnetometer,and it is 100 mV/μT.It is almost the same with the simulation value,error between the two is less than 1.5 percent.This simulation model is very helpful to understand the operation principle and transient response of the fluxgate magnetometer.It would be very important when designing a micro-fluxgate magnetometer.关键词
