Multi-Objective Trade-Off Quantification Based Design Optimization for Power Electronic Systems in More-Electric-Aircrafts

In this paper, a comprehensive formulation of reliability models for active and passive power components (i.e., capacitors semiconductor devices (MOSFETS)) regulated transformer rectifier unit (RTRU) more electric aircraft application is presented. Additionally, the work focuses on analysis evaluation at system level non-modular discrete MOSFET based auxiliary supply more-electric-aircraft. A rigorous quantitative assessment reliability, volume loss carried out component as well level, verifying how particular design relates to specific performance parameters. Keeping motivation, paper also studying analyzing inter-relation among other metrics such density efficiency taking 3kW RTRU an example design. The major under consideration study are failure in time (FIT), mean (MTTF), density, while keeping eye most prone elements converter - semiconductors. thermal management size, done choice switching semiconductors where candidate pool includes Si SiC technologies. From three different types widely used film, ceramic, aluminum electrolytic, it concluded that optimum choices high voltage DC link low-voltage output belong Aluminum Ceramic types, respectively. Finally, selection stage derived from extensive overall terms size reliability.
