摘要：A novel method of parallel switching power with different capacity in a controllable current sharing method is presented in this paper. It achieves proportional current sharing and stable output DC voltage by using controllable current sharing modes which output assignable feedback signals to the paralleling buck DC-DC converters. The validity and effectiveness are verified through comprehensive experiments. Output voltage is at range of 8.0±0.4V with energy transform efficiency of 80%. Moreover, controllable current sharing is established in a short time interval and it automatically recovers after removing the over current faults.
