摘　　要：为减小大功率开关电源启动电流对整流桥和滤波电容的冲击,设计了辅助电源启动电路。此电路采用基于DSP控制系统的两路开出信号来实现开关电源的软启动。实践证实该方法无冲击电流、成本低、体积小且简单实用。In order to reduce the high power switching power supply starting current to the rectification bridge and the filter electric capacity＇s impact,the accessory power supply starting circuit is designed.Two starting out signals of the DSP control system is used to realize switching power supply＇s soft start.The practice confirmed that this method has non-surge current,low cost,small volume and simple practical.
