The need to increase efficiency and reduce operating cost of shipboard DC power distribution networks results in a desire to increase the operating voltage of such installations to the medium voltage levels. Devices such as solid state bus-tie switches are an essential component of such systems, as they allow for system reconfigurations and prevent fault propagation across different sections of the system. This paper presents a scalable solid state bus-tie switch topology designed initially for low voltage power distribution networks, but easily scalable in terms of voltage and current. The use of a single active device greatly increases simplicity and reliability of the solution. The ability to extend the current and voltage ratings has been verified on the prototypes through extensive experimental tests in parallel and series connection, respectively. Several methods for fault detection are discussed and further verified experimentally.

“…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.…”

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.

“…The penetration growth of DC grids due to its advantages relative to its AC counterpart, given by lower losses and costs, reduction of conversion stages and easier integration to renewables, has increased in applications that vary from very high power high voltage systems [1], medium voltage submarine and vessels [2], down to low voltage microgrids [3]. This type of technology demands more stringent control and faster protection solutions, since fault currents usually have faster rise time and can be more damaging, due to the lack of zero crossing and capacitive input and output connection of power electronic converters.…”

DC Solid-State Circuit Breakers (SSCB) play an important role in the protection of DC and hybrid AC/DC systems. As they operate mostly in on-state, the use of widebandgap devices, with low conduction losses, is an attractive solution. These devices need to be selected based on the rare occasion of fault breaking, with associated overcurrent and overvoltage intervals. In this work a novel clamping circuit, consisting in its simplified form of Metal-Oxide Varistors and capacitors, is proposed to be used in a DC SSCB. This circuit has the objective to reduce the breaker overvoltage during protection, enabling a lower number of required semiconductors in series and consequent overall reduced losses. An analysis of the idea and operation principle of the system is presented, alongside its stages of operation and defining equations. To evaluate its benefits, the system is compared with one typical passive solution. At the end a scaled prototype is tested, validating the benefits and theoretical analysis of the proposed approach.
