Abstract
A system, comprising: a conductor having a pair of primary surfaces, the conductor including a through-hole formed therein, the conductor including a first notch that is formed adjacent to the through-hole; and a printed circuit board that is inserted in the through-hole, the printed circuit board having a current sensor mounted thereon, the current sensor being disposed inside the through-hole, the current sensor including a first magnetic field sensing element and a second magnetic field sensing element having respective axes of maximum sensitivity that are substantially perpendicular to the primary surfaces of the conductor.

A system, comprising:
- a first conductor having a pair of first primary surfaces, the first conductor including a first through-hole formed therein, the first conductor including a first notch that is formed adjacent to the first through-hole;
- a second conductor having a pair of second primary surfaces, the second conductor including a second through-hole formed therein, the second conductor including a second notch that is formed adjacent to the second through-hole;
- and
- a printed circuit board that is inserted in the first through-hole and the second through-hole, the printed circuit board having a first current sensor and a second current sensor mounted thereon, the first current sensor being disposed inside the first through-hole and the second current sensor being disposed inside the second through-hole, the first current sensor including at least two first magnetic field sensing elements having respective axes of maximum sensitivity that are substantially perpendicular to the second primary surfaces of the second conductor, and the second current sensor including at least two second magnetic field sensing elements having respective axes of maximum sensitivity that are substantially perpendicular to the first primary surfaces of the first conductor.
A system, comprising:
- a conductor having a pair of primary surfaces, the conductor including a through-hole formed therein, the conductor including a first notch that is formed adjacent to the through-hole;
- and
- a printed circuit board that is inserted in the through-hole, the printed circuit board having a current sensor mounted thereon, the current sensor being disposed inside the through-hole, the current sensor including a first magnetic field sensing element and a second magnetic field sensing element having respective axes of maximum sensitivity that are substantially perpendicular to the primary surfaces of the conductor.
A system, comprising:
- a conductor having a through-hole formed therein, the conductor including a first protrusion that extends from a first side of the through-hole towards a second side of the through-hole, the second side being opposite to the first side;
- and
- a current sensor that is disposed in the through-hole, the current sensor being disposed adjacent to the first protrusion, the current sensor being arranged to measure a level of electrical current through the conductor.
