AI Technical Summary
Technical Problem
Solid state circuit breakers are prone to failure modes such as short circuits, which prevent them from opening and can lead to detrimental consequences for the circuit interruption system and the load.
Method used
A system where a first circuit breaker, upon detecting a failure mode, requests an upstream circuit breaker to interrupt current flowing to it, allowing its mechanical contacts to open safely after the current drops to a predetermined level, and communicates a clear request to resume normal operation.
Benefits of technology
Ensures safe and rapid opening of mechanical contacts in the event of a solid state switch failure, minimizing disruption to downstream loads and enhancing system reliability.
