Abstract:
1. A current sensing assembly comprising: a conductor having a first side and a second side opposite the first side; a first magnetic sensor disposed proximate to the first side of the conductor and being structured to output a first voltage signal; a second magnetic sensor disposed proximate to the second side of the conductor and being structured to output a second voltage signal; a current direction detector circuit structured to detect a direction of a current flowing through the conductor using the first and second voltage signals and to output a switching signal based on the detected direction; 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 structured to receive the first and second voltage signals from the first and second outputs, the 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.
