Abstract
Official abstract text for this publication.
Embodiments relate to current difference sensors, systems and methods. In an embodiment, a current difference sensor includes first and second conductors arranged relative to one another such that when a first current flows through the first conductor and a second current, equal to the first current, flows through the second conductor, a first magnetic field induced in the first conductor and a second magnetic field induced in the second conductor cancel each other at a first position and a second position; and first and second magnetic field sensing elements arranged at the first and second positions, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. A current difference sensor comprising: first and second conductors arranged laterally asymmetrically relative to one another such that when a first current flows through the first conductor and a second current, equal to the first current, flows through the second conductor, a first magnetic field component contributed by the first current and a second magnetic field component contributed by the second current cancel each other at a first position and a sec…
