Contactless DC Circuit Breakers Using MOS-controlled Thyristors
전력용 사이리스터 MCT를 이용한 무접점 직류차단기
Abstract
Circuit breakers have traditionally employed mechanical methods to interrupt excessive currents. According to power semiconductor technology advances in power electronic device, some mechanical breakers are replaced with solid state equivalents. Advantages of the contactors using semiconductor devices include faster fault interrupting, fault current limiting, no arc to contain or extinguish and intelligent power control, and high reliability. This paper describes the design of a static
