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 power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).
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 .
One of the application of control systems in high-power inverters is to increase the speed and accuracy in achieving MPPT. Control algorithms continuously examine the input of the inverter and adjust its operational parameters to extract the maximum available power . Another essential factor is computational complexity.
This topology is optimized even when selecting the same power switches. For a three-level T-type inverter with a power rating of 11 kVA, we selected SiC devices with an RDS(on) of 75 mΩ and a blocking voltage of 1.2 kV for Q1 and Q2, and 60 mΩ and 650 V for Q3 and Q4 (see Figure 40).
In Ref. , a 9-level topology is proposed for a multilevel inverter, introducing a novel compact design. The goal of the proposed method is to increase the output power at a large scale, add more outputs, and enhance the topology.
