“…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.
