The effect of several modular approaches to the design, on the efficiency and size of a Solid State transformer (SST) are investigated. The modular approaches are evaluated for the case of 400 kVA, 10 kV/0.4 kV solid state transformers, considering the daily loading profile of the distribution network. The SST is compared to an equally rated low-frequency(More)
This paper presents the use of induction generator turbine machines with simplified frequency control as a direct drive solution for wind energy conversion. An offshore wind farm system is proposed utilising a VSC-HVDC connection. The wind farm will contain variable speed wind turbines driving Squirrel Cage Induction Generators (SCIG). The study will look(More)
This paper investigates the potential for size reduction of a Dual Active Bridge (DAB) DC-DC converter for a solid state transformer (SST) by implementing the converter in a highly modular manner. It is shown that when IGBT switches are used, a high degree of modularization of the DAB results in lower efficiency and increased overall transformer weight.(More)
Technological progress and development is bringing commercially available power supplies integrated in a single chip closer and closer to reality. One of crucial milestones in this process is integration of inductors with magnetic core onto a silicon substrate. Such inductors enable full integration of a switch mode voltage converter in a single chip,(More)
