High temperature, Smart Power Module for aircraft actuators

More electric aircraft require converters that can operate over a wide temperature range (−55 to more than 200°C). Silicon carbide JFETs can satisfy these requirements, but there is a need for suitable peripheral components (gate drivers, passives. . . ). In this paper, we present a “smart power module” based on SiC JFETs and dedicated integrated gate driver circuits. The design is detailed, and some electrical results are given, showing proper operation of the module up to 200°C.
