微型逆变器解决方案
微型逆变器在单个光伏 (PV) 电池板上转换电源，单个光伏电池板的额定功率通常为 400W，多个光伏电池板的额定功率则高达 1.5KW。微型逆变器通常基于两级式电源转换。首先，直流转直流阶段或升压电路将可变直流电压转换为固定直流电压（通常为 40 V 到 60 V）。同时，通过最大功率点跟踪技术（MPPT）能较大限度地从光伏板获取能量（通常 FSW = 100 KHz）。
首先在直流转直流阶段或升压电路将可变直流电压转换为固定直流电压（通常为 40 V 到 60 V）。同时，通过最大功率点跟踪（MPPT）技术保证从光伏板中提取最大电流。其次，在直流转交流阶段，逆变级将直流电源转换成与电网兼容的 1Φ 的交流电源。与组串式逆变器相反，微型逆变器可以连接一个、两个或四个光伏板，并分别对每个PV模块进行MPPT跟踪。

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.
