DEVELOPING AN HYBRID INTEGRO-DIFFERENTIAL FORMULATION 3D BASED ON THE ELECTRIC VECTOR POTENTIAL - APPLICATION TO THE CONDUCTIVE THIN SHELL STRUCTURE

Abstract

Electromagnetic modeling is becoming an increasingly important role,
especially in the design, manufacture and operation of electrical-electronic
devices. This paper develops a hybrid formulation coupled between the integral
and differential equations based on the electric vector potential, applied to
electrical devices with conductive thin-shell structure. The final equations were
solved by numerical methods. The advantage of proposed formulation is the only
meshing on the thin-shell without air-meshing, reducing the unknowns and the
memory computing. Through the modeling and calculation of electromagnetic
parameters for two classic problems and comparison with FEM 2D method, the
developed method was validated and proved applicable in practical problems.
