一、方案名称:
基于GD32F207ZE的光伏升压MPPT控制器
二、方案介绍:
此方案是采用GD32F207ZE作为主控制器的太阳能光伏充电控制器,可对以下主要的类型电池组实现充电管理:(铅酸电池组,普通锂电池组,铁锂电池组….等等)并且使用LCD显示光伏板电压,电池组电压和控制器温度(因为年末时间比较少,就简化了控制器的附加高级功能。(例如:可以再添加电流传感器,实现功率可控-发电电量累计和手机APP查看和设置参数。以及通过wifi实时上传物联网平台。。))有喜欢的利用本方案自己再添加高级功能。。。本控制器使用串口输入设置参数,为了后期可以使用蓝牙模块配合APP预留的功能,本控制器具有电池过压保护,控制器过温保护功能,夜间防逆流功能,
具有最大化利用光伏发电板,使其输出最大功率状态给电池组充电,实现绿色能源最大使用效益。。
三、方案结构框图:
四、设计应用描述及心得总结:
1. 使用的GD32F207资源配置:配置DMAIDLE方式接收串口数据,配置5个DMAADC通道获取数据,配置TIMER2 2个通道PWM输出控制,配置SPI1显示数据,配置内部FLASH作为设置参数的掉电存储
2. 使用SPI1驱动LCD引脚配置:PA5-SCL,PA7-SI,PA4-RES,PD0-RSX,PD1-CSX
3. 控制器供电使用了LM2596HVS降压12v给MOS驱动IR2110s供电以及(通过5v降压和3.3vLDO降压)提供单片机的供电。。最高支持60vDC输入(也可以使用XL7015替换,支持最高80VDC输入)
4. 不得不说,第一次使用GD32F系列的单片机,对GD32的库(使用非常方便,提供的历程也很多。有时间还是要继续再深入的学习)和STM32库的兼容性非常不错。可以节省很多的时间再去重新学习GD32的库使用函数了。。。
五、作品实物图+视频:
串口调试截图:
这个是小功率光伏板:
这个板子的功率非常小。。。电流只有180ma最大了。。。。。
移到楼下:换50w的光伏板
测试输入电压空载21v,输出23v电流:1.8a =41.4w的功率。。今天天气特别的好
视频里测试过程按了重启,为了方便观察mppt最大功率点的快速定位。。。
