Space Station Freedom, technology applications in vehicle electrical power systems

Abstract

This paper covers the Space Station Freedom electrical power system (EPS) design and shows how the application of that technology in aircraft (and other vehicles) electrical power distribution systems can reduce weight and volume, and improve reliability and maintainability. The design and development of the Space Station EPS was a major milestone in large-scale space power management and distribution. The challenge of distributing 100 kW of high-voltage DC power throughout the huge space vehicle led to the hardware development and testing of extremely reliable, lightweight, remotely controlled switchgear. This technology has been shown to be directly applicable in the electrical power management and distribution designs for such vehicles as commercial and military aircraft and ships.
