Abstract

This paper presents a magnetic circuit modeling of closed loop Hall-effect current sensors based on a magnetic equivalent circuit which could be simulated with a circuit type simulation software (PSPICE model). First, the principle of measurement of the closed loop Hall-effect current sensors is described, then, the magnetic equivalent circuit (MEC) modeling justified by the engineers´ model needs is elaborated. Finally the parameters identification protocol based on 3D Finite-Elements (FE) simulations and simplex optimization method will be presented.
