Learn About GaN
GaN System's Girvan Patterson discusses what GaN FETs can do for the design of automotive inverters. In one case, a GaN-based 12-kW inverter took the place of a silicon version weighing 70% more and occupying 80% more space. The device goes in mild hybrid vehicles and was designed by an automotive OEM.
This video covers a few details about the winner of Google's LiTTLE BOX challenge to create an inverter with 50 W/in.-cubed power density. The winner, CE&T in Belguim, used GaN Systems parts to create an inverter having 143 W/in.-cubed.
