Abstract
An arc fault sensor disposed on a circuit board proximate to a current carrying trace. The arc fault sensor includes a magnetic flux concentrator (MFC). The MFC includes a first flange and a second flange that are joined by a center post. Each of the first and second flanges have a cross sectional area that is larger than the center post. A sense coil winding is wound around the center post. The arc fault sensor generates an output voltage that is proportional to a rate of change of current in the current carrying conductor. For a given diameter of the sense coil winding, the output voltage is enhanced by the ratio of the cross-sectional areas of the flanges relative to the cross-sectional area of the center post. Methods of manufacturing and utilizing the aforementioned arc fault sensor are also disclosed.
