AUTOMOTIVE CURRENT TRANSDUCER BMS BDU PDU RCANV500H
A low-frequency fluxgate transducer is made of a wound core which saturates under low induction. A current chopper switches the winding’s current to saturate the magnetic core alternatively at ±B max with a fixed frequency. Fluxgate transducers use the change of the saturation’s point symmetry to measure the primary current. Due to the principle of switching the current, all offsets (electric and magnetic) are cancelled.
