In large-scale applications such as PV power plants, "high-power" in medium voltage (MV) inverters is characterized by the use of multilevel inverters to enhance efficiency and scalability. These high-power MV systems generally function within a power range of 0.4 MW–40 MW, and in certain applications, can reach up to 100 MW.
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 .

Modulation strategies are crucial in enhancing the performance of high-power inverters, particularly by reducing switching losses, minimizing harmonic distortion, and ensuring compatibility with multilevel inverter architectures . In high-power inverters, modulation techniques are employed to switch the circuit between these states.
In reviewing various PWM techniques in LS-PV-PP high-power inverters, we find that these techniques focus on optimizing the conversion of DC power from solar panels to AC power to inject an appropriate output power into the main grid.
One of the inherent issues in high-power CHB inverters is the imbalance in the output power, leading to instability and reduced current in grid-connected systems. Therefore, an adaptive control technique has been proposed to regulate the output power in these converters.
