说明：  提出了一种新型、方便、无损的电流采样法，其关键是用一个简单的RC 网络检测各路电流，然后在这种简单的电流检测方法的基础上方便、高效、低成本、简单地实现了对并联系统的均流，且均流效果好，误差在3 以下，电源输出稳定。
(A novel, convenient, non-destructive sampling of current law, the key is to use a simple RC network detection current separate ways, then this simple current detection method based on the convenient, efficient, low cost, simple to implement the mean flow of the parallel system, and both flow effect, the error below 3 , power output and stability.)
