| Abstract: | Miner lamp charging power was designed.Using half-bridge topology structure in design,having applied chip UC3907,so it resolved that electric current can't distribute averagely in module of converter.At the same time, used SG3525 chip two kind of output to control switch tube,it can make output voltage'accuracy high and steady by sampling.It applies to the mine successfully. |
