Electric vehicles (EVs) and hybrid electric vehicles (HEVs) are looking for solutions to power-conversion efficiency.

For a long time, most electronic power devices were based on silicon, a semiconductor that can be processed without generating virtually any defects. However, the theoretical performance of silicon has now been almost entirely achieved, highlighting some limits of this material, including limited voltage-blocking capability, limited heat transfer capability, limited efficiency, and non-negligible conduction losses. Wide bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), provide superior performance compared to silicon: higher efficiency and switching frequency, higher operating temperature, and higher operating voltage…
