The gradual evolution from hydro-pneumatic to electrical disposition of power in aircraft has placed stringent requirements on the reliability electronic components current and future aerospace applications. This paper examines prevalent state-of-the-art electronics provides an analytical overview More Electric Aircraft (MEA) vis-à-vis generation distribution within these aircraft. types devices currently employed for multiple conversion topologies are analysed weighed according their respective characteristics. Beginning with in-depth review failure modes available devices, highlights salient emerging Wide Band Gap (WBG) technologies such as Gallium Nitride (GaN) Silicon Carbide (SiC) draws extensive comparison counterparts. A comprehensive examination techniques estimation WBG revealed a number areas that merit due consideration. For instance, physics-based models have been developed assess operational lifetime silicon-based given require revamping light new materials unique physical characteristics possess. Similarly, condition monitoring techniques, respect primary secondary parameters, further investigation determine highly representative feature vectors best describe degradation devices. significantly, optimisation proposed health assessment needs be pursued through optimal use vital parameters. Keeping critical findings perspective, road map highlighting various avenues MEA is put forth apprise fraternity its growing significance.
