Abstract

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