Current detector in electric circuit of motor vehicle, has arithmetic processing circuit to calculate difference between electrical signals from two Hall elements placed between conductors, to detect current in conductors

摘要

Three conductors (11-13) are arranged branching radially from junction (O), at 120 deg from each other. Hall elements (21-23) are placed at equidistance from two adjacent conductors. An arithmetic processing circuit (30) calculates the difference between the electrical signals from two Hall elements, and detects the current flowing in the conductors. An Independent claim is also included for current detection procedure.
