DOI: 10.1109/access.2020.3029611
Abstract: The vacuum interrupter is widely used due to the advantages of no arc-extinguishing medium and high insulation strength. However, the arc voltage generated by the commonly used CuCr contacts is low. In hybrid DC circuit… read more here.

DOI: 10.1109/tcpmt.2019.2915764
Abstract: Hybrid dc switches have become increasingly prominent due to their low ON-state energy loss and less arc erosion in comparison with conventional semiconductor and mechanical switches. Zero-voltage switching (ZVS) is a common method for realizing… read more here.

DOI: 10.1109/tpel.2019.2924024
Abstract: In the flexible dc grid, the dc fault propagates extremely fast. It requires the dc protection and the dc circuit breaker (DCCB) can identify and isolate the fault line very quickly, for the healthy network… read more here.
