DC-SSCB Snubber for Electric Propulsion Ships With Effective Surge Voltage Reduction and Fast Dissipation of Fault Current Energy

IEEE Access
This paper proposes a snubber circuit for SSCB that performs voltage clamping operation in two stages to reduce surge voltage. The surge voltage is suppressed in the first stage using a MOV with low operating initiation and clamping voltages.
