Ultra-Light Tightly-Integrated Modular Aviation-Transportation Enabling Solid-State Circuit Breaker (ULTIMATE-SSCB)
06/21/2021 - 12/20/2024
A medium voltage direct current (MVDC) system provides lower distribution losses, higher power carrying capacity, and reduced conductor material compared with its low voltage alternative current counterpart. These benefits are critical to meet stringent weight and size requirements for aviation applications. The University of Tennessee will develop a lightweight, reliable, efficient, and flexible protection solution for future electrified aircraft propulsion systems that are expected to use a 1 kV to 10 kV MVDC distribution system. The team will develop a modular architecture with a highly integrated customized module, use advanced solid-state semiconductor devices cooled at cryogenic temperatures, and integrate protection intelligence to achieve project objectives.
