资料介绍

电源是电力设备中必不可少的组件,在保证用电设备工作稳定及可靠性上具有重要作用。开关调节式稳压电源转换效率高、体积小、重量轻,在电力设备领域有着广泛的研究与应用。论文设计一款以UC3842为控制核心的单端反激式多路输出开关稳压电源,介绍了反馈电路、输入输出整流滤波电路、过压过流保护电路等的设计。实验结果表明,该设计提高了开关电源的转换效率,降低了电压调整率,同时具有稳压性好、纹波系数小等特点,在电力设备领域中有良好的应用前景。

As the essential component in the electrical equipment, the power plays an important role for ensuring the electrical equipment works stably and reliably. With the characteristics of high efficiency, small volume and light weight, the switch power supply is researched and used widely in the electrical equipment. In this paper, a multi-channel output single-end fly-back switching voltage power supply based on the UC3842 chip was developed. Moreover, the design of the feedback circuit and the rectifier filter circuit as well as the over- voltage protection circuit was introduced. The experiment results show that the design which has the character- istics of high-stabilization and small ripple factor can improve the conversion e...
