- •
A lumped-element method for modelling transformers i demonstrated.
- •
The method can include hysteresis and arbitrarily complex geometries.
- •
Simulation results for one power transformer are compared to measurements.
- •
An analytical curve-fitting expression for static hysteresis loops is shown.
