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.

用于船载配电网络的固态母线联络开关

船用配电网络设计的最新趋势，例如从交流到直流的过渡，给配电网络保护问题带来了新的挑战。诸如固态母线开关之类的设备通过快速分离网络的故障部分并防止额外的能量馈入故障，提供了防止低阻抗故障在整个配电系统中传播的第一道防线。本文提出了一种用于船载配电网络的固态母联开关的新拓扑结构。考虑到其工作原理，对拓扑进行了彻底的描述，并使用了一个小规模的原型来验证其操作性能。在开环和闭环操作中展示了电流中断能力，
