Co-Simulation of Low-Frequency Electromagnetic Device Coupled With Complex Electrical Circuit Based on the PGD Approach

To study a low-frequency electromagnetic device represented by a finite-element (FE) model coupled with a complex electrical circuit, an approach based on the co-simulation principle can be investigated. Then, each component of a system is solved by a dedicated software. To reduce the computation time of a co-simulation, an approach based on the proper generalized decomposition (PGD) method that is a model order reduction (MOR) approach is investigated. The proposed approach is evaluated using three examples: a single-phase inductance coupled with a simple circuit equation, a three-phase transformer connected to a rectifier supplying a variable electrical load, and a system composed of four FE models coupled with electrical equations.
