“…1 (b). Some upgraded versions of SSCB, such as active thyristor-based DCCB [11], SSCB with self-adaptive fault current limiting capability [12], self-powered SSCB with fault current limiter [13] etc., are proposed. Though SSCBs are faster in response, they cause higher conduction loss and do not provide galvanic isolation.…”

The DC power system, due to its convenience of conversion, integration, and use, is getting immense attention in the field of power transmission and distribution. It is superior to traditional AC systems in terms of efficiency, reliability, and control simplicity as well. A DC circuit breaker is one of the important elements of any DC power system. It is a sophisticated technology designed to break DC current only. The breaking of a DC current is always challenging compared to the breaking of an AC current, as DC current does not have natural zero crossing points like AC current has. Moreover, DC current breaking becomes more critical when the current is inductive as energy stored in the network inductance opposes instantaneous current breaking. Hence, this energy needs to be absorbed and dissipated as heat during the current breaking operation, which is exactly what is done in the traditional DC circuit breaker topologies. This paper introduces a new topology for DC circuit breakers with a mechanism to reuse this stored energy instead of dissipating it. The mechanism is analogous to regenerative braking in electric drive systems and can enhance the overall system efficiency. The proposed scheme was analyzed through rigorous computer simulation and was experimentally validated.

“…However, additional tracks allow dc fault current commutation to energy dissipation with quick fault isolation response. The development in solid‐state and hybrid dc‐CBs has solved issues within the fault isolation response [51, 52], but the higher cost and relatively larger imprints still require attention. Besides, dc‐CB or MMC with fault‐blocking capabilities, the dc–dc converters can achieve isolation of the faulted section in the transmission line.…”

“…Not only do the characteristics of the SSCB meet the opening speed and control accuracy requirements of PSE, but the SSCB also has a short cooling time and can thus be used for continuous multiple-PSE operation. Therefore, according to the technical requirements of PSE, a new power electronic device based on the SSCB is designed in this paper, and insulated-gate bipolar transistors (IGBTs) are used as the opening element [18] , [19] .…”
