功率优化器解决方案
直流转直流功率优化器将光伏电池板的可变直流电压转换为固定直流电压。
这个过程也被称为最大功率点跟踪 (MPPT)。MPPT技术可以在任意环境条件(包括辐射水平和温度变化)下,充分实现功率提取的技术。MPPT 可以直接或单独通过安装在每个光伏面板上的单个单元工作,也可以在逆变器的前级降压/升压单元,配合串联在逆变器输入端的多个光伏板工作。
在光伏面板上安装一个功率优化器还可以实现快速关断功能 (RSF) ,在一些地区,家用太阳能逆变器必需具备快速关断功能功能。独立的功率优化器要在恶劣的户外条件下运行,所以外观小巧,工作高效,使用寿命长是其成功的关键要素。
英飞凌提供各种不同封装和技术的产品,包括硅 (Si) ,碳化硅 (SiC) 和氮化镓 (GaN) 。因此,英飞凌可帮助制造商为单面板和多面板微型逆变器设计实现优化、高效的解决方案。
