Abstract
A current detector comprising a current-path conductor in the form of a piece of sheet metal having a slit cut therein for providing a U-shaped path for the flow of current to be detected or measured. A Hall generator is held opposite the current-path conductor so as to be contained in the slit therein, as seen in a direction normal to the sheet-metal current-path conductor, for generating a Hall voltage indicative of the magnitude of the current flowing through the U-shaped current path. A magnetic overlay covers part of the current-path conductor for a higher sensitivity of current detection through enhancement of flux density acting on the Hall generator.
