摘要
实现了一种通过单片机控制开关电源使光伏电池给蓄电池充电的设计方案。系统使用单片机控制反激式开关电源,并精确采样电压值和电流值,形成反馈。采用最大功率点跟踪(MPPT)算法,实现了系统工作的高效率。软件和硬件都对系统进行了保护,实现了系统工作的安全性和可靠性。此外给出了实际使用结果,由结果可知,系统工作正常,达到了预期的性能。
This design uses a photovohaic module to charge a sealed lead-acid battery by using a microcontroller to control a powersupply.It uses a MOTOROLA micro-controller to control fly-back power supply and samples the voltage and current precisely to form a feedback loop.This design realizes the high-efficiency by using MPPT arithmetic.It realizes the safety and reliability of system by using hardware and software protection.This thesis gives a real result and the system works oroperly and achieves anticipate performance.
