ABSTRACT:
Methods and systems for detecting changes in currents are disclosed, including: dividing a main current into two or more subcurrents, combining a first magnetic flux of a first subcurrent of the two or more of the subcurrents with another magnetic flux of another current to generate a combined magnetic flux, and sensing the combined magnetic flux to determine relative changes between the first subcurrent and the other current.
