Technical scope

In particular, the development of the future power electronics based power systems as an enabler for the future net-zero system will be discussed.

The conference will address the entire value stream, from top level system perspectives, over technology innovation and power electronics modelling and control.

For each theme, the session will begin with a keynote speech/ presentation on the “so what” of the topic area, and the key action areas/ priorities that relate to it.

This may be selected from the paper submissions where appropriate or informed by the content of those.
