Medium frequency transformer for railway traction: Soft switching converter with high voltage semi-conductors

2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2008
Nowadays, in railway traction, in order to reduce the weight and the size of the input transformer, several structures using intermediate medium frequency stages are under consideration. The major problem is to reach a high switching frequency with high voltage devices.

Multiobjective Optimization of Medium-Frequency Transformers for Isolated Soft-Switching Converters Using a Genetic Algorithm

IEEE Transactions on Power Electronics, 2017
The main challenge of medium-frequency transformers is the number of design parameters, constraints and objectives, and the difficulty of handling them on a particular design. This paper presents a novel computer-aided optimal design for MF transformers using a multiobjective genetic algorithm, in particular the nondominated sorting genetic algorithm ...
