Abstract

Different types of fluxgate excitation circuits were used and some simplified models were proposed for the analysis of excitation. This paper presents an analytical solution of the non-linear circuit which is fed by a squarewave voltage source. Experimental results show that this solution can be used to evaluate the overall excitation performance. Special attention is drawn to the effect of the amplitude and phase of the excitation current on the efficiency and offset stability. The solution serves as a tool for fluxgate magnetometer designers.
