Abstract: Fluxgate current transducer including a control circuit and a fluxgate device comprising a saturable soft magnetic core surrounded by an excitation coil, the control circuit comprising an excitation coil drive circuit connected to the excitation coil configured to generate an alternating magnetic field to alternatingly saturate the soft magnetic core. The excitation coil comprises a first winding and a second winding connected together at a common point forming an input of the first winding and an output of the second winding, the first winding connected in series to a first switch (S1) and the second winding connected in series to a second switch (S2).
