    Description

    An electric aircraft powertrain includes four parts: fuel cell power sources, DC-DC converters, DC-AC inverters, and loads. In this poster, the fuel cell provides 3.6 MVA (2.5MW) electricity energy, which is converted to the required electric energy form of the load using DC-DC and DC-AC converters. The fuel cell offers 600-900 volt DC voltage, which converts to a fixed 1000VDC, and subsequently, the DC form converts to the AC electricity form using the DC-AC inverter. The DC-AC inverter's design, including power module selection, is described based on power loss and thermal analysis. The power losses, including conduction and switching losses, are derived to find the inverter efficiency and the junction temperature. The junction temperature of the power module is analyzed based on the derived power losses and thermal resistance among the ambient temperature at the junction of the power module. Furthermore, thermal analysis is performed to assess the power module's temperature distribution and thermal management requirements under different operating conditions. The simulation results, obtained using MATLAB and PLECS software, validate the mathematical analysis and provide a comprehensive understanding of the system's behavior.
