In the context of PV power plants, the "high-power" classification for multilevel inverters usually applies to systems operating in the MW range, incorporating medium voltage levels of 2.3–13.8 kV to optimize energy transmission efficiency and support reliable system performance .
However, its dependency on precise system modeling might bring instability in the presence of parameter variations or unmodeled dynamics . One of the application of control systems in high-power inverters is to increase the speed and accuracy in achieving MPPT.
The high-power inverter with a NPC topology, also known as a three-level inverter, is a type of multilevel converter. In contrast to traditional two-level inverters, which have two voltage levels (positive and negative), this inverter has an additional intermediate voltage level known as the neutral point .
The main circuit of an inverter includes an inverter DC power supply, IGBT bridge inverter, protection circuits, high frequency high voltage transformers, and high frequency high voltage silicon stack (Rectifier).
