This research case describes the key role of recently emerged wide-bandgap semiconductor devices, especially Silicon Carbide (SiC) devices, to minimize the dimensions of the offshore converter stations. It highlights the revolutionary breakthrough in development of high voltage wide-bandgap (WBG) power quantum devices and proposes design of an optimisation tool, validated by experimental prototypes, to provide accurate estimation of space by selecting different converter topologies and device technologies. The 2 investigators aim to report on the effectiveness of SiC devices in size-reduction of offshore stations and its specific reliability criteria.
