| Abstract: | This article analyzed the working procedure of switching power supplies in detail. In order to avoid the second breakdown of power transistors,the authors apply a RC absorption net, and bring forward a way of reducing the transistors' switching losses through optimizing base drive and then improve the capabilities of switching power supplies. |

| Keywords: | switching power RC absorption net optimizing base drive |
