Recent trends in shipboard power distribution network design, such as the transition from ac to dc, result in new challenges on the issue of distribution network protection. Devices such as a solid-state bus-tie switch provide the first line of defense against the propagation of low-impedance faults across the distribution system by quickly separating the faulty portion of the network and preventing additional energy to be fed into the fault. This article proposes a new topology of a solid-state bus-tie switch for shipboard power distribution networks. The topology is thoroughly described considering its operating principles, and a small-scale prototype has been used to verify its operational performances. Current interruption capabilities are demonstrated, both in the open- and closed-loop operations, with fault detection and decision algorithms implemented on a stand-alone controller.
