Abstract

Fluxgate sensor provides very good resolution and accuracy for measuring the Earth’s magnetic field, which is critical to comprehend space weather. Fluxgate sensor drive electronics for satellite communications employ an oscillating signal to periodically saturate and unsaturate a magnetic core material, producing a distinctive voltage at the output of the sense coil that changes with the external magnetic field. This paper describes the design and simulation of fluxgate sensor drive electronics, which can be used to drive the excitation coil in fluxgate magnetometer sensor (FMS). The excitation coil’s electronics circuit consists of a drive oscillator, frequency divider, and voltage to current converter. In order to achieve the aim of this work, the software that was used for the simulations was based on the NI Circuit Design Suite 11.0 from the National Instruments. This is due to the versatile nature of this software. Several simulations were performed to find the best excitation frequency required to saturate the fluxgate magnetic core material. The first analysis step carried out was the evaluation of the optimum excitation frequency and current value, which guarantees the ferromagnetic core material to saturate a given geometrical dimension of the excitation coil. By carrying out the simulations using different excitation frequencies, a peak current of 29.3mA was observed to be sufficient to drive the chosen excitation coil with a 5 kHz square wave.
