摘要
基于单片机设计了电机励磁回路用双路输出数字开关电源,首先介绍了变换器主电路工作原理;提出了关键电路的硬件设计和系统结构框图,分析了双路输出数字开关电源的软件设计,给出了主程序和测量模块流程图。
The Double Output Digital DC-DC Switching Power Supply based on MCU （microcomputer unit） which used by electrical machines＇excitation is designed in this paper.First the principle of the Digital DC-DC Switching Power Supply is introduced briefly,then the design of its hardware and the structure diagram is shown.Furthermore the software design of the Digital DC-DC Switching Power Supply are analyzed with the flow chart of the main program and the measure module.
