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

Alfred Rufer, Alejandro Rujas, Irma Villar, Asier Garcia Bediaga

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 us ...

New Parametric Model of Medium-Frequency Single-Active-Bridge Converters

Alfred Rufer, Philippe Barrade, Alejandro Rujas, Irma Villar, Asier Garcia Bediaga

This paper presents a new parametric model of a single-active-bridge (SAB) converter with a variable number of phases. The soft-switching behavior and the design of snubbers are also analyzed. The analytical study is validated using PLECS simulation softwa ...
