A Review of technologies for MVDC circuit breakers

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Medium voltage direct current (MVDC)
distribution networks have been considered for various
applications, such as offshore wind farm collector systems, allelectric
naval vessels, and aircraft. MVDC circuit breakers are a
critical technology to directly manage faults in multi-terminal DC
(MTDC) networks. However, DC current breaking is much more
challenging than in AC systems because there is no natural zerocrossing
of the current waveform to aid fault isolation. This
paper reviews existing MVDC circuit breaker technologies and
also discusses their advantages and disadvantages. This paper
also introduces new topologies that can be applied in MVDC
applications. The operation of several hybrid DC circuit breaker
topologies with aided commutation is included. The paper
illustrates that a hybrid DC circuit breaker with aided
commutation can clear a fault within 2-5 msecs with low losses,
this shows great potential for future MVDC applications. The
implications for the practical design of commercial MVDC
circuit breakers are also discussed.
