Abstract

Space and cost limitations are inherent in installing magnetic core individually as the magnetic flux concentrator (MFC) of a multi-conductor current sensing system. In this study, we first examine the basic and compact MFC structure derived from the magnetic core for multi-conductor current sensing systems. Then we propose and experimentally verify the curved trapezoidal MFCs with covering the dense magnetic field area to further improve the amplification ratio. The design increases sensitivity considerably and is crucial when the sensing currents are extremely low.
