Technological study of an IGBT module for an aeronautical application in zone engine

The non pressurised zones of aeroplanes raise the problem of the choice of power components. The motor nacelle is a non pressurised zone and the IGBT modules are therefore subjected to strong combined constraints: thermal, mechanical (vibrations, shocks), pressure/depression/damp. The power IGBTs ar...

Summary:The non pressurised zones of aeroplanes raise the problem of the choice of power components. The motor nacelle is a non pressurised zone and the IGBT modules are therefore subjected to strong combined constraints: thermal, mechanical (vibrations, shocks), pressure/depression/damp. The power IGBTs are located inside a closed but not airtight box containing the complete inverter (IGBT modules, busbar, capacity, drivers and electronics control). The components are subjected to severe aeronautic constraints. There is wide experience as regards the reinforcements to be added to the electronic cards in order to meet reliability demands; the choice of the structure and the IGBT module technology has still to be solved
