基于51单片机的风光互补充电器的设计

Design of the Portable Wind/Pv Hybrid Controller Based on the MCU 51

基于单片机89C51和60W小型风光互补发电系统的研究,设计了一个小功率风光互补充电控制器,更便携的将分散的风能、太阳能转变为电能储存在蓄电池。控制核心89C51通过检测电路对整个系统实时管理和监控,51的一个定时器产生高频PWM配合蓄电池的BUCK充电路实现对蓄电池的智能充电。最后通过matlab软件对60W风光互补发电系统仿真,仿真结果表明风光互补电源系统的安全性和可靠性。

Based on the research of 89C51, the single-chip microcomputer, and 60W small scenery complementary power generation system, a low-power wind-Pv hybrid charging controller was designed, which could be more portable and turn the wind and solar energy into electrical energy stored in batteries. Through monitoring and managing the whole system by detecting and using a timer of 89C51, a high frequency PWM was generated to finish battery intelligent charging.Finally through the simulation of 60W wind-Pv hybrid power system in the MATLAB,the results showed that the wind-Pv hybrid system was safe and reliable.
