Solid-state transformers are nowadays a highly attractive research topic, both in academia and industry. Various topological proposals have been made and several demonstrators have already been deployed. A solid-state transformer is a galvanically isolated converter with power electronics interfaces on its terminals and isolation achieved at arbitrary high operating frequency of an integrated medium/high-frequency transformer. Since at least one of the terminals is intended for direct MV connection, this brings many technological challenges related to implementation of modular power electronics stages, insulation and overall system integration besides the application of high switching speed medium voltage power semiconductors and new measurement technologies required for performance evaluation. The workshop focus will be on the key technologies needed to further advance solid state transformers concepts:

• MV Transformers: magnetic materials, winding technologies, modeling, insulation coordination, design optimization
• Power Semiconductors: Wide-band gap devices, high frequency switching, soft switching techniques, packaging and integration
• System Integration: Advanced designs of PEBBs, CELLs, sub-assemblies for solid-state transformers
• Measurement Techniques: Soft-Switching and on-state loss measurement of MV power semiconductors, loss measurement of passive components, characterization of insulation materials.

All presentations and discussions will be in English language.
