GaN-based electric vehicle charger boast over 97% efficiency, 2.6 kW/l power density
Prior to this achievement, Level-2 EV chargers reached maximum efficiencies of 94%, the researchers claim. Using GaN Systems’ 60 A, 650 V GS66516T switches in an innovative two-stage architecture, the Kettering University research team, led by Associate Professor of Electrical Engineering, Dr. Kevin Bai, were able to increase the wall-to-battery efficiency to more than 3% greater than previously obtained.
“The switching performance we observed with the GaN Systems’ parts was marvelous. Using these devices our power electronics exhibited a power density greater than 2.6 kW/l. This is a significant milestone with important implications for charging electric vehicles, among other charging applications”, stated Dr. Bai, characterizing this new development as a ‘game changer’ for the EV charging industry.
