“…In our previous work [2,3], it has been demonstrated that this new functionally for VSC can be achieved by proper selection of converter topology and by adopting a revised switch realization scheme that uses the newly emerging robust power electronic devices such as ETO [8][9][10]. The use of VSC as CB (circuit breaker) is significant, mainly: i) It eliminates the need to use separate circuit breakers that need to be developed specifically for DC current interruption.…”

“…Traditional techniques for protecting dc systems [7,8] induce an oscillating current to produce a current zero, and thereby to permit the interruption of the fault current in mechanical switches. Such techniques require additional components such as switches, charging or discharging capacitors, pre-charging circuits and power supplies.…”

We show that medium-voltage dc power buses can be protected against short circuit faults by coordinating the action of a converter that supplies power to the bus with the action of contactors that are used to reconfigure the bus connections. Following a fault, the bus is de-energized (so there is no large current to interrupt), one or more contactors are reconfigured, and the dc bus is then reenergized. For a typical industrial dc bus, we show that it is possible to execute this deenergize-reconfigure-re-energize process 10 times faster than an AC bus can be protected and reconfigured using traditional circuit breakers. We show how the de-energizing and reconfiguring times depend on the output capacitance of the main converter and on the distance to the fault, and we show how to size each hold-up capacitor so that loads on unfaulted circuits can ride through the process uninterrupted.

“…Furthermore, current limited MCBBs in combination with upstream current limited power electronic converters present additional complications [4], [5]. The purpose of this paper is to address three significant issues that have been identified as a result of developing a DC distribution system for a shipboard application.…”
