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

High-Power Machines and Starter-Generator Topologies for More Electric Aircraft: A Technology Outlook

“…Indeed, the use of WBG devices is generally advantageous for reducing losses and for increasing switching frequency, which again can influence the power density. The characteristics of WBG devices are also expected to support higher reliability of PEC units for MEA applications [95]. Furthermore, especially silicon carbide (SiC) devices have the potential to enable the hightemperature operation of PEC interfaces.…”

Advanced aircraft power electronics systems — The impact of simulation, standards and wide band-gap devices

“…Power modules are therefore now being developed that are demonstrating these improved characteristics for aircraft power systems [21] however some important challenges remain which need to be understood and solved by the power electronics designer. The most important issue for the module or circuit designer is thermal management.…”

Simulations and Measurement Analysis of SiC MOSFET and IGBT Gate Drive Performance in Power Modules for More Electric Aircraft Motor Drive Applications

“…This can result in lighter systems, with reduced fuel burn and a subsequent positive impact on the environment. Electro-hydrostatic (EHA) and electro-mechanical (EMA) actuators are driven by electrical motors that can be controlled and monitored by a Power Drive Electronics (PDE) system [2]. This PDE interfaces with the flight controller and can drive the motor using closed-loop control.…”
