Title: High Power Medium Frequency Transformer Design Optimization

With increased interest in Power Electronic Transformers or Solid State Transformers, several technical problems arise related to actual realization of these technologies. Irrespectively of adopted power electronic topologies, these structures are characterized as being modular and having inherently built-in galvanic isolation at medium or high frequency. Designing a high-power high-voltage medium frequency transformer is associated with multiple technical challenges related to electrical, magnetic, dielectric and thermal performance limits encountered in the system. Various technological choices must be carefully considered and selected before being included into a generic multi-objective optimization. Tutorial will provide an overview and address challenges coming from the application area, characteristics of involved materials and available design choices, associated modeling of different elements impacting medium frequency transformer design, as well as optimization process as whole. Multiple illustrative design examples will be critically analyzed in terms of their key performance indicators, and supported with practical examples realized by the tutorial instructors themselves.
