Circuit Breaker. A circuit breaker is a type of switch that is designed to interrupt the flow of nominal, abnormal, or fault current. Whenever a high magnitude of current flows through the circuit, the circuit breaker works as a mechanical device that can easily cut off the power supply and protect the electrical system from damage.
Although conventional electromechanical circuit breakers have a proven record as effective and reliable devices for circuit protection, emerging power distribution technologies and architectures, such as dc microgrids, require improved interruption performance characteristics (e.g., faster switching speed). The need for faster switching …
