基于STM32的嵌入式系统电源管理设计

Design of Power Management for Embedded System Based on STM32

如何让嵌入式设备在保持体积不变的情况下为其提供稳定可靠的电源,是嵌入式设备使用中面临的重要问题之一。基于此,设计了一种功耗低、体积小、性能稳定的电源管理系统。首先介绍了基于单片机STM32F4的管理系统的设计框架,然后分别阐述各个子模块的工作原理与设计,最后介绍了系统电量测量以及开关机的软件设计,并对电源管理系统进行测试。实验结果表明,该电源管理系统达到了预期的设计要求。

It is must to face the important issues that how to make the embedded device to keep the volume of the case to provide a stable and reliable power supply, embedded devices in the use and market development. Based on this, a low power consumption, small size, stable performance of the power management system is designed in the article. Firstly, the hardware design framework of management system based on STM32F4 is introduced, and on this basis, introduced the work of each sub-module principle and design. Finally, it＇s introduced the overall software design of the system, test the power management system. The experimental results show that the design of the power management system to achieve the desired design requirements.
