单片机在开关电源设计中的应用

Microcontroller Applications in Switching Power Supply Design

本文介绍一种基于单片机的开关电源设计方案,设计出一款可以方便对电压进行调节的实用开关电源。利用单片机对电源的输出进行调节,同时用单片机扩展A/D转换器检测输出端的电压,将检测结果传回单片机,形成反馈机制,即可以手动对输出进行调节也可以自动的根据设置进行调节。

This paper describes a based on a single-chip switching power supply design, design an everywhere voltage regulating the use of switching power supply. Use of the microcontroller to adjust the output of the power supply, while with MCU extend the A/D converter detection output voltage, the detection result transmission callback tabulating machine, to form a feedback mechanism, which can be adjusted manually on the output can also be automatically according to the settings adjustment.
