With the D3GaN technology, the CO2 footprint can be reduced by over 1.4t relative to silicon solutions, during a lifecycle of a BEV, by improving the efficiency of the inverter. The technology is designed for the highest reliability as it uses the widest gate voltage, which can withstand the harsh gate voltage stress induced by the inductive design of the inverter application. With this solution, BEV can save 50% on power losses over the driving cycle of the electric car, thus reducing battery cost and increasing driving range and performance. This solution also reduces the cooling system requirements and the size of the BEV inverter.
