集中式逆变器解决方案
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。
