Finite Element Approach for Computing Stray Fields in Magnetic Shielding Due to Non-Sinusoidal and DC Hybrid Excitations

Traditionally, electromagnetic problems that involve both magnetic and non-magnetic components have been tackled using sinusoidal sources at a 50Hz frequency. However, the effectiveness and suitability of large-scale modeling and simulation in the face of intricate stimulation scenarios remain evolving requirements, presenting modern researchers with a collection of intricate challenges to surmount this obstacle. In this study, a finite element method is extended for magnetic vector potential formulations to calculate stray field losses (magnetic fields, eddy current losses) in magnetic shieldings due to non-sinousoidal and DC hybrid excitations in the excitation coils. The obtained results will have provided a detailed description of the magnetic field distribution, eddy currents, and power losses in the electromagnetic shielding plate for hybrid excitations. The application of the devloped method is validated on the Benchmark problem (TEAM Problem 21 Family).
