船舶直流固态功率控制器技术研究

摘要

To distinguish the states of subcircuit overload,impact and short⁃circuit in DC power distribution system for ships,protect the system and suppress impact or short⁃circuit current,a novel DC solid⁃state power controller for 24 V DC power distribution system is studied. The main circuit design,control strategy and inverse⁃time over⁃current protection design of the power controller are discussed emphatically. Finally,the feasibility of the DC solid⁃state power controller for ships is verified by the principle prototype.%为了实现船舶直流配电系统支路负载过载、冲击、短路状态的区分与保护，抑制冲击或短路电流，针对典型的直流24 V配电系统，研究了一种新颖的船舶直流固态功率控制器。重点讨论该功率控制器的主电路设计、控制策略、反时限保护设计。最后通过原理样机，验证了船舶直流固态功率控制器技术的可行性。
