| 摘 要： | 针对目前电流环的设计方法不明确的问题，通过建立DC／AC系统的动态模型并对该模型进行理论上的推导和分析得出了电流环的设计方法．该方法在系统参数不完全明确的情况下，电流内环尽量采取PI调节器，将使系统的稳定性更好，参数调整比较方便，能满足一定的带宽和动态特性．通过仿真实验验证了理论推导的正确性．

| Abstract: | Concerning the designing scheme being obscure at present, the design method of current loop was obtained via establishing the dynamic model of DC/AC system and analyzing it theoretically. The PI adjustor was given priority to being used in the current loop in the circumstance of the system parameter being indefinable, which have the advantages of better system stability and easier parameter adjustment, and meet the demand of a certain bandwidth and the dynamic characteristics. By simulation it shows the design scheme is available. |
