project title: ''mtmp-hvdcsst: multiterminal multiport high voltage direct current solid state
transformer enabled by an oil-immersed 30kv/1mw sic converter submodule (csm) with >150kv insulation
capability''
this project is developing a revolutionary multi-terminal multi-port high voltage direct current
solid state transformer (mtmp-hvdcsst) converter station to replace traditional, high-cost, and
bulky hvdc substations. to enable this architecture, the team will design and manufacture next-
generation mosfet power modules and a highly efficient, oil-immersed sic converter sub module (csm)
featuring ultra-high insulation capability. ultimately, this hardware will drastically reduce the
cost and physical footprint of integrating offshore wind energy while accelerating the transition
toward scalable, reliable, and highly efficient multi-terminal dc grids.
