摘要
从低压电器发展的趋势出发,介绍了智能控制模块对供电电源的要求。简述了直流稳压电源的两种实现方式,着重对这两种电路进行了对比分析。最后由两个自行设计的开关电源引出了两种电源设计方案,并且通过其中一个设计实例详细介绍了输入电路、输出电路、反馈电路、变压器缓冲电路的拓扑选择和器件选型。
This paper introduces the demand of intelligent control model to the power supply based on the developments of low voltage electrical Appliances. It gives a simple describes of two DC regulated power supply designs and focus on the comparison between them. Eventually, this paper gives two kinds of power supply designs and gives a detailed introduction of the input circuit, output circuit, feedback circuit and clamp circuit.
