Abstract:

Aircraft power systems' development increasingly reflects the objectives of the aviation community to increase system reliability, reduce environmental impact, and increase efficiency by means of lower energy use.   One of the key reasons of this change is the inclination towards greater voltage power distribution.   This paper analyzes the possibility of raising voltage levels as a means of improving aircraft power system performance especially in view of the More Electric Aircraft (MEA) concept.   By reducing power loss, minimizing conductor weight, and enabling more compact and effective power conversion choices, high-voltage designs provide a strong road toward future aircraft electrification.   Simulation and modelling of MEA-based electrical topologies for a range of voltage levels forms the method to evaluate their effects on thermal management, safety margins, redundancy of the system, and overall efficiency.   Moreover, by means of intelligent control systems and next-generation materials, our work solves such issues like insulation, electromagnetic interference, and fault tolerance.   Using higher voltage systems not only advances technology but also strategically toward fully electric or hybrid-electric flying since it helps to accomplish the more general goal of sustainable aviation.
