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。

最优系统解决方案的价值
Infineon’s Easy family’s tremendous growth in the past few years led Easy modules to become even more flexible and scalable in key areas, such as voltage class and topologies.
As a result, Easy modules are widely used, not only in industrial applications but also in automotive applications.
To continue the successful momentum created by Easy 3B, “the big brother of the family”, Infineon has successfully developed the Easy 4B package, extending the package’s capabilities even further!
The EasyPACK™ 4B is now the largest package in the Easy family, with three DCB substrates.
In this training, we will see how Infineon’s two-level slew-rate control (or 2L-SRC) gate driver IC can help overcome gate resistance dimensioning trade-offs in order to obtain reduced switching losses.
We will also see an example of gate resistor dimensioning, with an under-five V/ns voltage slope target, as usually seen in drive applications.
Let’s learn more about how solar inverters work, from the ones we have in our houses, to the ones that are applied in major factories. We will also see how Infineon innovates in power semiconductors for solar inverter technology and how that can help with reducing costs and time to market.
In this module, we will have a look at different solar inverter trends and how the technology is evolving.
And afterwards, we will see what Infineon’s comprehensive solutions for the positioning of solar applications are.
In this EiceDRIVER™ X3 digital isolated gate driver training you will learn how to install the software that aids you in the evaluation of X3 digital and its evaluation board.
