Design of a 150kW transformer with integrated series inductance for future aerospace applications by using artificial NN

Abstract:
The future of transportation hinges on the electrification of all vehicles. This article presents a novel design methodology for high power transformers in DC-DC converters dedicated to propulsion, specifically targeting voltage levels between 600 and 1.2 kV for next-generation regional electric aircraft. Utilizing an artificial neural network (ANN), we establish an initial design benchmark for general specifications. Subsequently, we refined this design based on detailed specifications and established design rules, achieving a transformer with integrated series inductance of 20 kW/L integrating the liquid cooling. This work paves the way for more efficient and powerful electric propulsion systems in aviation.
