Researchers have presented a new design that, in tests, enabled gallium nitride power devices to handle voltages of 1,200 volts. That’s already enough capacity for use in electric vehicles, but the researchers believe that further work can boost its capacity to the 3,300-to-5,000-volt range, to bring the efficiencies of gallium nitride to the power electronics in the electrical grid itself.
