A Novel Bidirectional Solid-State Circuit Breaker for DC Microgrid

IEEE Transactions on Industrial Electronics, 2019
DC microgrid has attracted more and more attention due to its unique characteristics, but the development of a dc microgrid is also facing some challenges, such as interruption and isolation of short-circuit fault currents. Therefore, the dc circuit breaker plays an important role in ensuring the normal work of a dc microgrid.

New Simple-Structured AC Solid-State Circuit Breaker

IEEE Transactions on Industrial Electronics, 2018
Recently, distributed generators and sensitive loads have been widely used. They enable a solid-state circuit breaker (SSCB), which is an imperative device to get acceptable power quality of ac power grid systems. The existing ac SSCB composed of a silicon-controlled rectifier requires some auxiliary mechanical devices to achieve the reclosing ...

Diode Clamped Solid-State Circuit Breaker: A Novel Solid-State Circuit Breaker without Dynamic Voltage Unbalancing Issues

2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020
In this paper, a new solid-state circuit breaker for medium voltage applications is proposed named Diode Clamped Solid-State Circuit Breaker (SSCB). Unlike the conventional medium-voltage SSCBs using simultaneously operated switches in series to block medium level voltage, Diode Clamped SSCB utilizes a novel diode clamped topology to extend its ...
