Transphorm proposes to demonstrate a normally off fast high voltage Gallium Nitride power switch solution. The switch would block to 1200V, have a threshold voltage greater than 5 V, and the phase 2 switch will target an on resistance less than 15 ohm-mm and current more than 1 Amp. To accomplish these targets, Transphorm will combine the design requirements of realizing a high (and positive) threshold voltage while maintaining a low total on resistance while maintain a low switching resistance. The device will target low dc to rf dispersion or achieve a dynamic on resistance which is within 2x of the static performance. The switch would ultimately be capable of switching at high frequencies (1 MHz or higher) with efficiency in excess of 97%.
