Summary

The worldwide electrification of the transport sector requires the development of highly efficient and cost-effective power electronic components. Further the demand towards high integration of power electronic components is continuously rising.

Gallium nitride (GaN) semiconductor technology is the enabler for highest DC/DC / Onboard charger (OBC) efficiency as well as power density for automotive application. Especially the efficiency increase is demonstrating significant sustainability improvements of electrification technologies due to a significant reduction of energy losses during charging.

Finally, the forceful usage of GaN based OBCs and DC/DC converters lead to savings of CO2 equivalent losses that are comparable to the savings that can be reach by changing over from Si to SiC inverter.
