集中式逆变器配合许多紧密相连的太阳能电池板转换功率。其额定功率从600 KW 到 3000 KW 不等。集中式逆变器通常基于单级功率转换,大部分逆变器采用变压器设计或隔离变压器设计。在直流转交流阶段,可变直流电可以转换成与电网兼容的交流电。
在该变换单元, 两电平或 三电平 NPC1、NPC2、ANPC 拓扑都可选用。三电平拓扑因其效率更高而被广泛使用。1000 V光伏 (PV) 系统通常首选 三电平 NPC2 拓扑。1500 V光伏系统越来越受欢迎,因为它们可以降低系统成本,提高端到端效率。三电平 NPC1 / ANPC 拓扑结构使逆变器设计更稳健,更能抵抗宇宙射线。开关频率和冷却要求是影响交流滤波器尺寸、系统容量和成本的关键因素。需要具有低损耗和高电流密度的功率模块。

Our modern world has a huge electric energy demand. The Earth gets more solar energy in one hour than the entire world uses in a year. Stay tuned to learn more about residential solar energy set-ups and Infineon solutions.
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.

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.
