Abstract:
A current sensing assembly includes a conductor, first and second magnetic sensors disposed proximate to opposite sides of the conductor and being structured to output first and second voltage signals, a current direction detector circuit structured to detect a direction of a current flowing through the conductor, a switching circuit having first and second outputs and being structured to switch between a first condition where the first voltage signal is output to the first output and the second voltage signal is output to the second output and a second condition where the first voltage signal is output to the second output and the second voltage signal is output to the first output based on the switching signal, and an output circuit including a differential amplifier structured to amplify a voltage difference between the first and second voltage signals and to output the amplified voltage difference.
