The energy transition will require power electrical devices able to manage high voltages and high currents. Although today’s electronic converter’s market is dominated by silicon-based technology, these electronic devices have elevated intrinsic losses due to silicon physical limited properties. Thanks to their physical properties Wide-Band-Gap (WBG) semiconductors such as silicon carbides (SiC) or Gallium Nitride (GaN) or even Ultra Wide-Band Gap (UWBG) semiconductor such as diamond, Ga2O3 or AlN are particularly interesting for power electronic.
