The main purpose of this study is to adapt a 28V battery-powered super-lift Luo converter topology to the aircraft systems by adding the interleaving feature. It is aimed to have better efficiency compared to conventional designs. F-22 military aircraft and civil aircraft such as Boeing 787 use 270V DC for battery systems. New standards for the avionics using 270V DC may not apply to older avionics. Therefore, conversion from 28V to 270V can be an advantageous application for both new and old systems. As a result, an interleaved super lift Luo converter has been designed to increase the voltage from 28V to 270V with a quite high conversion ratio so existing old systems stay up-to-date due to developments. Analysis of this new interleaved super lift Luo converter was carried out with a double-loop PI controller. The topology uses silicon carbide MOSFETs as high-frequency switches. This paper shows the design philosophy of the converter and proves the system with simulations.
