| Abstract |
This paper describes the design, construction and performance of a 5 kVA aviation power modulecontaining silicon carbide MOSFETs. The function and control of this module within a commercialaviation power electrical control unit (ECU) application is explained and the power dissipationbenefits from the use of these MOSFETs instead of silicon IGBTs when driving an electrical motorcontrolling an aileron are presented. The paper shows the calculated reliability figures for the powermodule in this application and an application-specific reliability test to verify 150,000 flight hours ofmodule operation is introduced. Performance test results from a prototype unit are also presented. |
