Abstract

Abstract: In order to explore the influence of excitation circuit parameters on the current of probe of three-tips fluxgate magnetometer, and provide a proper theoretical foundation for designing transformer parameters, a novel mathematical model is proposed based on transformer coupling and probe’s self-inductance through numerical analysis. The numerical results and the actual tests are matched. The proposed method provides a powerful help to design parameters of excitation circuit, and make further study on the relationship between circuit parameters and excitation current.

Key words: semiconductor, fluxgate magnetometer, transformer, square-wave excitation
