| Abstract |
In recent years, DC distribution systems are becoming hot issue due to the increase in digital loads and DC generation systems according to the expansion of renewable energy technologies.[1,2] However, removing the fault current in DC grids is comparably difficult since the current in DC grids has no zero-crossing point like in AC grids.[3] Thus, developing dedicated DC circuit breakers for DC grids is necessary to get safety for people and electrical facilities.[4] This paper proposes magnet arc extinguishing method to develop a 300[VDC]/10[A] DC circuit breaker. The performance of the proposed DC circuit breaker was verified by an experimental circuit breaker test system built in this research. |
