A Comparison Between the Circuit Theory Model and Finite Element Model Reactive Components
This paper presents two different modelling techniques for the reactive components of a partial-core transformer; a circuit theory model and a finite element model. Each model was used to simulate a hypothetical partial-core transformer with a varying winding aspect ratio and the results compared. Analysis of the simulation results suggested modification of two parameters of the circuit theory model, the leakage function and the magnetising function. The models were then compared to test results from three different partial-core transformers that were built.
