Characterization of Radiated Electromagnetic Fields Using Equivalent Sources with HGAGWO Method

This article presents modeling approach for characterizing electromagnetic disturbances radiated from power electronic devices. The approach is based on the replacement of the real device by an equivalent dipole network (electric and magnetic dipoles). The set of dipoles radiates the same near-field of the device under test. The dipoles are determined from a near-field cartography obtained by measurement bench. The parameters of these dipoles are calculated by solving an inverse problem with a fast and stable optimization method, Hybrid (HGAGWO) (Davahli et al. in J Ambient Intell Humaniz Comput 11:5581–5609, 2020 [1]) involving genetic algorithms (GA) (Holland in Adaptation in natural and artificial systems, 2nd edn. The University of Michigan Press, Ann Arbor, MI, 1992 [2]) and the gray wolf optimizer method (GWO) (Faris et al. in Neural Comput Appl 30:413–435, 2018 [3]). The purpose of this method is: provide a simple representation of power electronic devices, and decrease the time required to perform electromagnetic compatibility (EMC) simulation.
