| 摘 要： | 针对多个开关电源并联时易出现负载电流在各模块间分配不均的现象,介绍了常用的负载电流自动均流法——平均电流自动均流法及其工作特性。并针对其存在母线电压降低的缺陷,提出了一种改进的平均电流自动均流方法,经试验证明均流精度比较高。

| Abstract: | Aiming at the phenomena of uneven current that easily occurs when parallel connection of several switch powers is carried out,the paper introduces the averaged current automatic current sharing method and its characterists.Aiming at its defect that the voltage of share bus will fall when power does not run or goes wrong,the mending current sharing method is advanced. By experiment,the method is testified to be higher precision. |
