Arc-less commutation in hybrid DC circuit breaker

2016 IEEE International Conference on Plasma Science (ICOPS), 2016
DC circuit breaker (DCCB) has been intensively studied due to increasing demand in DC power transmission, such as mega solar power plants and large wind farms. A hybrid DC circuit breaker which consists of electrical contacts, semiconductor devices and a metal-oxide element (varistor) is a promising device to provide a small contact resistance and a ...

Multi-Port Hybrid DC Circuit Breaker for DC Distribution Network

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
The two-port hybrid DC circuit breaker (TP-HCB) combines the advantages of mechanical DC circuit breaker (DCCB) and solid-state DCCB, which has small loss during normal operation and fast action speed. However, the TP-HCB contains many IGBTs to withstand transient breaking voltage, therefore the total cost of TP-HCB is relatively high.

Experimental tests on a superconducting hybrid DC circuit breaker [PDF]

, 2016
Direct Current (DC) transmission systems are widely recognized offering significant potential for long distance high power delivery. DC circuit breakers are a key enabling technology for managing faults in multi-terminal DC networks (MTDC). However, DC current breaking is much more challenging than in AC systems because there is no natural zero ...
