✓ Extracting the parasitic capacitance matrix of the transformer
✓ Connecting the transformer FEM model with a circuit such as rectifier and filter
✓ Computing Iron and copper losses in the transformer
✓ Determine the temperature rise due to electromagnetic losses
✓ Examining the stresses and deformation in the transformer due to electromagnetic forces
✓ Extracting material property data using curve digitizer
✓ Solving convergence issues by rectifying BH curves
✓ Using data from manufacturer's datasheet to model the material behaviour and electromagnetic losses
✓ Obtaining Effective BH curve model from the original material BH curve
Requirements

Description
This course delves deep into various aspects of transformer modelling. It covers electromagnetic analysis, electromagnetic loss calculation, coupled electromagnetic-thermal analysis, electromagnetic-structural analysis and finally, various aspects of magnetic material non-linearity modelling.
It is structured in the form of simple tutorial videos demonstrating how to extract magnetizing and leakage inductances, parasitic capacitances, FEM-circuit coupling with rectifier and filter, iron and copper loss calculation, thermal analysis, structural analysis and BH curve modeling.
A basic e-core transformer geometry is used for ease of understanding. Each consecutive tutorial builds up on the previous step to develop a comprehensive understanding of transformer multiphysics simulations. For more complex geometries, the approach and procedure for simulation remains the same as discussed in this tutorial series.
