This technology makes a more efficient DC power grid possible, paving the way for cheaper, reliable electricity.

This paper proposes a dc circuit breaker for voltage source converter (VSC) based high-voltage dc transmission (HVDC) systems. Technical challenges for applying dc circuit breakers are to increase ...

This paper presents two high-voltage direct-current circuit breakers that have the capability of interrupting a short-circuit current within several milliseconds. They consist of a current-limit ...

But what exactly is a circuit breaker in Covid terms? The UK, Northern Ireland, Singapore and Israel have all previously used circuit breakers to try to reduce their coronavirus cases.
