“…With the development and contribution of power control systems between 1980 and 1990, the growth of solid-state switches became remarkable, whose predominant material is silicon (Si), such as SCR [58], IGBT [6,59,60], IGCT [61], GTO [62], and CS-MCT [35]. Si devices have a high level of maturity and are commercially available with a wide range of voltages and currents.…”

“…Compared with the IGBT or the SiC Mosfet, the CS-MCT and the thyristor can offer lower conduction losses and stronger tolerance to current and voltage surges, but need additional forced commutation technology. As a result, the breakers based on thyristors or the CS-MCT are attractive in terms of higher power efficiency and more robust fault isolation [35].…”

This paper deals with circuit breakers (CBs) used in direct current microgrids (DCMGs) for protection against electrical faults, focusing on their evolution and future challenges in low voltage (<1.5 kV) and medium voltage (between 1.5 kV and 20 kV). In recent years, proposals for new circuit-breaker features have grown. Therefore, a review on the evolution of circuit breakers for DCMGs is of utmost importance. In general terms, this paper presents a review concerning the evolution of circuit breakers used in DCMGs, focusing on fuses, mechanical circuit breakers (MCBs), solid-state circuit breakers (SSCBs), and hybrid circuit breakers (HCBs). Their evolution is presented highlighting the advantages and disadvantages of each device. It was found that although modern circuit breakers have begun to be commercially available, many of them are still under development; consequently, some traditional fuses and MCBs are still common in DCMGs, but under certain restrictions or limitations. Future challenges that would allow a successful and adequate implementation of circuit breakers in DCMGs are also presented.

“…In recent years, DC power systems have come to the fore in microgrid and distribution systems, configuring DC-based renewable energy such as PV and battery charging stations [1,2]. These features have prompted DC applications in shipboards, airplanes, telecommunication systems, and data centers [3][4][5]. However, fault detection and isolation to a fault area are still major technical barriers of DC-based systems.…”

Ensuring a protection scheme in a DC distribution system is more difficult to achieve against pole-to-ground faults than in AC distribution system because of the absence of zero crossing points and low line impedance. To complement the major obstacle of limiting the fault current, several compositions have been proposed related to mechanical switching and solid-state switching. Among them, solid-state circuit breakers (SSCBs) are considered to be a possible solution to limit fast fault current. However, they may cause problems in circuit complexity, reliability, and cost-related troubles because of the use of multiple power semiconductor devices and additional circuit configuration to commutate the current. This paper proposes a SSCB with a coupled inductor (SSCB-CI) that has a symmetrical configuration. The circuit is comprised of passive components like commutation capacitors, a CI, and damping resistors. Thus, the proposed SSCB-CI offers the advantages of a simple circuit configuration and fewer utilized power semiconductor devices than the other typical SSCBs in the DC microgrid. For the analysis, six operation states are described for the voltage across the main switches and fault current. The effectiveness of the SSCB-CI against the short-circuit fault is proved via simulation and experimental results in a lab-scale prototype.
