Recently there have been widespread used distributed generators and sensitive loads. It enables solid-state circuit breaker (SSCB) an imperative device to get acceptable power quality of AC power grid systems. The existing AC SSCB composed of SCRs requires some auxiliary mechanical devices to achieve the reclosing operation before fault recovery. But the new AC SSCB can achieve the quick breaking...
Recently according to the development of DC transmission which is high efficiency, stability of DC grid has become a major concern. Therefore, the reliable DC SSCB (Solid-State Circuit Breaker) is required in order to secure high safety. The previous DC SSCB is unstable and many elements are required in order to perform the operating duty. This paper proposes a new DC SSCB. Since the proposed DC SSCB...
There is no zero crossing of the current in DC power circuits. Thus unless you cut off the short-circuit current quickly, the electrical fire caused by electric arc or spark can occur. And after the initial fault breaking operation the long-duration sustained interruption without fault recovery may cause a lot of serious economic losses. Therefore this paper proposes a new DC SSCB that has quick reclosing...
These days, widespread use of sensitive loads and distributed generators makes solid-state circuit breaker (SSCB) an essential component in power circuits to achieve a high power quality for AC Grids. In the case of previous AC SSCB using SCRs, some auxiliary mechanical devices are required to make the reclosing operation possible before fault recovery. However, the proposed AC SSCB can break quickly...
