摘要
随着宇航、新能源汽车和军事武器等应用领域的快速发展，电子设备的数量和复杂性大大增加，同时为了增大配电系统的负载兼容性和带载能力，传统的机械式继电器和常规式断路器已经无法满足供配电系统的高可靠配电要求。具有继电器通断功能和断路器保护功能的智能固态功率控制器应运而生。本文对比分析了直流固态继电器和固态功率控制器的开关特性和保护特性，最后通过实验验证直流固态功率控制器的基本功能。

Abstract
With the rapid development of aerospace, new energy vehicles, military weapons and other application fields, the number and complexity of electronic equipment has increased greatly. Meanwhile, in order to increase the load compatibility and carrying capacity of distribution system, the traditional mechanical relay and conventional circuit breaker have been unable to meet the high reliable distribution requirements of power supply and distribution system. Intelligent solid-state power controller with relay on/off function and circuit breaker protection function came into being. In this paper, the switching characteristics and protection characteristics of DC solid-state relay and solid-state power controller are compared and analyzed. Finally, the basic functions of DC solid-state power controller are verified through experiments.
Key words： DC Solid-State Power Controller; Solid State Relay; Switching Characteristics; Protective Properties
