EM FE Method Applied for Transformers Design – e-lesson#7 – Electromagnetic Theory

Master’s level Thursday, 6 August 2026, 2:00 PM TZ Europe/Zagreb

Hosted by: Zlatko Hanic

Presents the theoretical electromagnetic concepts underlying advanced transformer modelling.

This lesson introduces the theoretical electromagnetic framework required for advanced transformer simulations. Participants explore Maxwell’s equations and their relevance to electromagnetic modelling. The lecture explains how magnetic energy, co-energy, and inductance are represented in numerical models. The behaviour of nonlinear magnetic materials and saturation effects are also discussed. Participants gain insight into how theoretical electromagnetic principles are translated into computational formulations used by simulation software.

Learning Outputs

  • Understand Maxwell’s equations in the context of transformer modelling
  • Explain magnetic energy and co-energy concepts
  • Interpret nonlinear magnetic behaviour and saturation
  • Relate theoretical principles to FEM simulations
