本文介绍了一种基于MCU的四旋翼无人机智能电源管理系统设计和实现方案。本系统以STM32 MCU为控制核心，以TI公司的降压控制器LM5117和CSD18532KCSMOS为核心器件，由滤波模块、稳压模块、电压反馈模块、AD控制模块，显示模块组成。利用LM5117的DC-DC功能和反馈模块，系统不但实现了动力系统要求的恒压恒流功能，此外还具有过流保护功能以及负载识别能力；通过抑制电源纹波的产生,满足了控制系统的低噪声纹波电压的要求，另外系统进行了抗干扰设计。
power management system design and implementation scheme. This system with the STM32 MCU as the core, by TI company LM5117 and CSD18532KCSMOS step-down controller as the core device, by filtering module, voltage regulator module, AD module, voltage feedback control module, display module. Using LM5117 DC - DC function and feedback module, the system not only implements the function of constant pressure constant current power system requirement, moreover also has the function of over-current protection and load identification ability; By inhibiting the production of power supply ripple, satisfy the control system of low noise ripple voltage requirements, the other system anti-interference design.
