What is a high-power MV inverter?

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.

Which voltage source inverter is best?

Single and three-phase inverters are subdivided into two-level voltage source inverters (VSI) and MLIs. For various applications, MLIs are the best choice because they can overcome power quality issues and improve the THD in the output waveform while providing high efficiency and reliability [53, 54, 55].
