Abstract
A current sensing device comprises N coil elements, arranged in annular or polygonal configuration. Coil at i=1 is adjacent coil at i=N, and coil at i=x is adjacent to coils at i=x−1 and i=x+1. Each coil comprises a plurality of wire winding layers comprising innermost and outermost wire winding layers that are electrically connected to each other. The outermost layer of coil at i=1 is connected to a terminal via an electrical link. The outermost layer of coil at i=y is connected to innermost layer of coil at i=y−2 via an electrical link. Outermost layer of coil at i=2 is connected to a terminal via an electrical link. Outermost layer of coil at i=z is connected to innermost layer of coil at i=z−2 via an electrical link. Innermost layer of coil at i=N is connected to innermost layer of coil at i=N−1 via an electrical link.
