基于stm32的Buck-Boost数控电源

资源内容介绍

项目描述：使用干电池作为电源，经稳压、滤波模块向电路供电，选用 MOSFET 作为开关，使用 PWM 控制开关状态，选择 GS8558－SR 作为驱动芯片，输出电压、电流经运算放大器输入到 stm32，通过 AD 转换获取电路状态。其中，电路处于连续工作模式，用户可通过按键控制该数控电源的输出电压，使用 OLED 显示电路参量。独立完成了该项目，包括电路设计、参数计算、元件选型、PCB 设计、仿真验证以及控制程序编写。涉及技术：Buck－Boost 电路，multisim，嘉立创 EDA，GPIO，ADC，定时器输出 PWM 波形，标准库
