正在轨道上组装的国际空间站（ISS）使用的是120v直流电力系统，是大型空间电力系统的一个很好的例子。在使用高压直流的大型空间电力系统中，为了防止故障传播，提供过载和故障保护，隔离故障负载和设备，必须在电力管理和控制系统的开关设备上采用具有限流功能的固态型电源开关装置。为日本实验舱（JEM）电力系统研制并组装了固态远程电源控制器（RPC）。RPC具有通过功率器件（功率MOSFET）在有源区域运行来限制短期过流的独特能力。本文介绍了大型空间电力系统中作为RPC最基本功能模型的CLS（限流开关）的开发方法。本文将通过实验和分析对CLS进行评价。本文还将展示CLS在上下游网络协同下的实验结果。
The International Space Station (ISS) being assembled on orbit is using 120 V DC electric power systems and one of good example of the large-scale space power systems. In order to prevent the fault propagation, provide protection against overload and fault, and isolate the faulty load and equipment in the large-scale space power systems using high voltage direct current, a solid state type of power switching device which has the current limiting function must be applied to the switching gear for the electric power management and control system. A solid state remote power controller (RPC) has been developed and assembled for the Japanese Experimental Module (JEM) electric power system. An RPC has a unique capability to limit short term over-current through the power device (Power MOSFET) operation in the active region. In this paper, the approach of the developing the CLS (current limiting switch), which is the very basic function model of the RPC, will be described for the large-scale space power systems. The evaluation for the CLS by experiment and analysis will be shown in this paper. The experiment result of the CLS in the network coordination with upstream and downstream will be also shown in this paper.
