New high-voltage power electronic converters and facilities for transmission grids tend to have multiple power switches at different floating potentials. Moreover, the trend goes towards the use of power switches with higher operating voltages (up to 10kV), in order to reduce the number of switches by system.
Globally, the energy landscape is shifting; the generation of electricity is moving towards greener energies, to incorporate more and more renewable power. Transmitted over continents and oceans, transmission lines are spanning over longer distances when connecting power generation areas to consumers. How can we help making this international electrical network of the near-future into a reality?
