It predicts an operational lifetime of 158,000 years at a continuous 20 V gate bias and reduces overall system costs by approximately 30%. Its switching frequency increase from 600 Hz to 10,000 Hz can boost power density by over 300%, while achieving a 99% conversion efficiency reduces thermal requirements by up to 50%. The device also replaces mechanical switching in pulsed power applications, improving efficiency and control.
