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.
