Exploring Redundant High-Voltage Architectures for Electric Aviation

Electric aviation is a much-needed technical advancement in this era. Most developed nations are shifting towards cleaner and greener energy solutions, and developing electric aircraft is part of that initiative. This work conducts a comprehensive study on the development of high-voltage electrical architectures for small- to medium-range electrical aircraft. The process follows defining KPIs based on which the architectures will be assessed. Starting from basic structures, the study systematically grows the basic design into more extensive and more general architecture families, each representing fundamentally unique configurations and features. Each proposed architecture was critically reviewed to identify its strengths and limitations, particularly in terms of redundancy, scalability, and performance under different operational scenarios. The final step involved evaluating the architectures against set criteria for a comparative review to guide future applications and development in the design of high-voltage electrical aircraft.
