摘要
针对部分光伏离网逆变器无缝切换,设计了一种基于STM32芯片的控制电路,并实现了包含MPPT充电、逆变优先切换,并能够完成充电自动管理的单芯片光伏一体机。该机集成通信控制等功能,解决了多芯片协同工作问题。最后通过实物实验进行了验证,性能良好且满足设计要求。
This paper designs a control circuit based on STM32 chip for the seamless switching problem of some photovoltaic off-grid inverters,and implements a single-chip photovoltaic integrated machine that includes MPPT charging,inverter priority switching,and can complete automatic charging management integrated communication control and other functions.It solves the problem of multi-chip cooperation.Finally,it is verified by physical experiments,and the performance is good and meets the design requirements.
