一种用于微电网保护的Δ型直流断路器

Conventional Z-source-type circuit breakers exhibit inherent drawbacks, such as noncommon ground, significant source-side fault currents, and a narrow autonomous breaking range causing misoperation. To address these issues, this article proposes a novel bidirectional △-source circuit breaker topology. The △-source circuit breaker utilizes a three-winding coupled inductor, which can generate a high...
