Abstract

DC microgrids are getting more and more used to distribute energy in more efficient way. Nonetheless, the protection of DC circuits against cur- rent faults becomes challenging due to the absence of zero current cross. Typical current Solid State topologies present high on-state losses. Hence, The present Masters Thesis pursues the construction and experimental val- idation of a Solid State Circuit Breaker featuring a significant loss decrease in comparison with an IGBT breaker of similar power range. This Mod- ern Circuit Breaker topology unites the strengths of different semiconductor devices in expense of augmenting its control complexity. Therefore, a sim- ple control strategy is proposed.
