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.
