阐述传统电源系统在可靠性方面存在的问题。本设计利用DSP对电源系统模块进行检测和控制,并通过旁路故障模块接入正常模块提高电源系统整体可靠性,该系统综合利用数字和模拟电路,使传统空间电源智能化从而达到更高可靠性,同时利用数字芯片对各模块电源进行管理,提高了模块的精确度和寿命。通过试验测试,电源系统在模块发生故障情况下,实现了对模块的隔离和冗余设计,对于调压方案,本设计进行逐点采集,实现了数字对模块的调压控制。
Describe the reliability of the traditional power system problems. This design uses DSP to detect and control the power system module, and access the normal module through the bypass fault module to improve the overall reliability of the power system. The system makes full use of digital and analog circuits to make the traditional space power intelligent so as to achieve higher reliability At the same time, the digital chip is used to manage the power of each module, which improves the accuracy and life of the module. Through the test, the power system in the case of module failure, to achieve isolation and redundancy of the module design, for the voltage regulator program, the design of point-by-point acquisition, the realization of the digital control of the regulator module.
