Design av kostnadseffektivt DC-baserat uppsamlingsnät för innanhavsvindkraftspark medelst seriekopplade högfrekvenstransformatorer

In this project, the design of a medium frequency transformer for inland sea is proposed. The design is intended for applications when the series coupling of the output of multiple DC/DC converters on their high voltage side is done to achieve high voltages for collecting energy from wind parks, where today expensive platforms are needed to accommodate the heavy 50 Hz transformers. The focus is on the isolation of medium frequency high voltages which should at the same time be able to dissipate the heat produced from the losses. The work builds on a three years collaboration between RISE and Chalmers around a PhD project and has resulted in one journal article and 2 conference publications so far. The goal is to determine what power density can be achieved at different frequencies and output voltages. The work begins with the determination of the study case and the isolation study, and then the project is finalized with the design and verification of a prototype and LCC calculations.
