High Temperature Inverter for Aerospace Application.

This paper reports the design, the fabrication and experimental performances of a 2 kW, 20 kHz, High Temperature, Three- Phase, all-SiC JFET Voltage Fed Inverter (VFI). The inverter includes a specific JFET driver circuit and a DC-link capacitor. All these elements have been validated over a wide ambient temperature range, between 25 °C and 200 °C. The power device used, a 1200 V, 15 A, JFET from SiCED has been characterized up to 200 °C. Additionally, an innovative and reliable protection circuit for normally-on devices is also presented and validated. [ABSTRACT FROM AUTHOR]
