MVDC grids are increasingly present in the existing AC systems regarding integration of renewable energy resources. This creates the need to master the design of medium-frequency transformers, one of the key components of modern DC transformers.

DC transformers are regarded as the key enabling components for future MVDC power distribution networks. Such a device unifies power conversion, insulation and protection into a single power electronics system. The voltage adaptation and galvanic isolation are provided by the transformer.
This paper presents the design and development of a 1 MW, 5 kHz medium frequency transformer prototype, which combines specific technologies regarding cooling and insulation. The design is achieved with the help of a model-based optimization tool, built around elaborate analysis and modeling of transformer specific phenomenon concerning its electrical operation.


This whitepaper presents a MW-rated medium frequency transformer design and explains:

  • how to design and implement liquid-cooled hollow copper conductors as windings,
  • what to keep in mind when windings are oil-immersed for insulation purposes,
  • how to use nanocrystalline as magnetic core material.
