Excitation Circuit for Fluxgate Sensor using Saturable Inductor

Original language description

Traditional excitation circuits for fluxgate sensors consist of a lossy resistor or a bulky inductor (operated in non-saturated mode), whose function is to limit the excitation current. As a result, a high voltage source is required to provide sufficientexcitation current to the sensor. For these reasons, traditional excitation circuits are unsuitable for portable battery operated devices that use fluxgate sensors. In order to reduce the circuit size and operating voltage in such applications, the useof a saturable inductor is proposed in this paper. Practical methods for choosing suitable circuit components are described to ensure that the circuit operates under optimum conditions. Experimental results illustrate a good linear relationship between the second harmonic voltage and the measured current for a fluxgate dc current sensor using the proposed excitation circuit.
