DESCRIZIONE The target of the thesis is to build a complete 3D design flow for a power planar transformer for motorsport applications (F1, FE, WEC and others).
The design of a planar transformer will start with the analytical magnetic sizing.
This initial step provides a preliminary design framework, utilizing MATLAB/Excel tools for precise calculations of the transformer's operational points.
Following the magnetic sizing, Finite Element Method (FEM) simulations are conducted using Ansys (Maxwell and 3QD software). These simulations offer deeper insights into the electromagnetic and thermal behaviours of the transformer, enabling the identification and optimization of critical design parameters like core and copper losses, and the evaluation of the transformer's efficiency under various load conditions.
Additionally, FEM simulations are used in estimating parasitic elements, which are crucial for accurately predicting the transformer’s performance in the high-frequency range.
Also topology studies, with several transformers in replacement of a bigger one, can be considered.
The thesis activity will be carried out in collaboration with the R&D department of the Marelli Motorsport with and expected duration of 6-9 months.
