摘要
在一个直流分布式电源系统中,各独立设计的电源模块或子系统之间的相互作用,可能导致整个系统的不稳定.在小信号的意义下,系统稳定性能通过测定阻抗比Zo/Zi来判断.在讨论已有的基于阻抗分析法的直流分布式电源系统稳定性研究成果和存在问题的同时,改进了单独负载阻抗规范的禁止区域,不仅保证小信号系统的稳定性的充分条件,而且给实际测量系统的稳定裕量提供了一条方便的途径.
In a DC distributed power system, the interaction between individually designed power modules/subsystems may give rise to the instability of the whole system. In the small\|signal sense, these interactions can be predicted by checking impedance ratio Z/\-o/Z\-i. This paper summarizes our work in these areas, and introduces the method of 'individual load impedance specification'. This method is not only a sufficient condition to ensure samall\|signal system stability but also leads to a very simple engineering approach to measure the system stability.
