NASA spacecraft could benefit from significant weight savings as well as increased safety, x-57 Maxwell aircraft, GL-10 hybrid electric VTOL aircraft, HEIST project could replace heavy electromechanical relays in the power system with lightweight, fast Solid State Power Controller (SSPC) modules. The SSPC modules can also be incorporated into the front end of motor speed controllers and allow the controllers to safely disconnect from the DC bus in the event of a short circuit fault within the controller. The modules also will have use as battery pack disconnect switches in the event of a pack failure that could short circuit the main power bus.
LaunchPoint Technologies is providing a gen-set and hybrid power system to a potential customer for evaluation on a small UAV they are planning to manufacture and sell. This customer has expressed a desire for circuit protection to enable the vehicle to survive the failure of a motor speed controller that could short out the entire DC bus of the vehicle. Other UAV manufacturers that wish to conduct operations over people will eventually need to meet some airworthiness requirements and circuit protection that allows the vehicle to remain in the air after a short circuit in a feeder wire or other single point electrical failures will be essential to demonstrate airworthiness to the FAA. Eventual electric powered Personal Air Vehicles will require high power and low weight circuit protection to enable safe reliable ubiquitous flight.
