Abstract

Recent breakthroughs in Silicon Carbide (SiC) material and fabrication technology have led to the development of High-Voltage, High-Frequency (HV-HF) power devices with 10-kV, 15-kHz power switching capability. Programs are underway to demonstrate half-bridge modules with 15-kV, 110-A, 20-kHz capability in the next few years. The emergence of HV-HF devices with such capability is expected to revolutionize utility and military power distribution and conversion by extending the use of Pulse Width Modulation (PWM) technology to high voltage applications.
