摘　　要：为了满足新一代航天器模块化、智能化和小型化的配电要求,设计一种高精度模拟式固态功率控制器(SSPC),用较少的硬件电路实现了反时限过流保护电路的高精度拟合,同时兼具小型化和高性价比的特点。仿真与实物验证结果表明:采用文章设计的SSPC,反时限过流保护精度在5%以内,具有较高的工程应用价值。In order to meet the modular,intelligent and miniaturized power distribution requirements of the new generation of spacecraft,a high-precision analog SSPC(solid-state power controller)is designed.High-precision fitting of inverse time limit overcurrent protection circuits is achieved with less hardware circuits,while being both miniaturized and cost-effective.The results from simulation and physical verification show that the SSPC mentioned in the paper has a high engineering application value with the inverse time limit overcurrent protection accuracy within 5%.
