Abstract:
A method for measuring electric current applied to a load includes: with a sensor element having an inaccuracy, measuring an electric current supplied to a load to produce a measurement of the electric current; with the sensor element, measuring the electric current with an added perturbation current; and using measurements of the electric current taken with and without the perturbation current to refine the measurement of the electric current.
