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.
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.
At present, the types of high-voltage inverters include thyristor current-type inverters, diode-clamped multilevel inverters, fly-across capacitor-type multilevel inverters, cascaded H-bridge-type multilevel inverters, modular multilevel inverters, etc. In [5, 6], a current source inverter is introduced.
Medium- and high-voltage motors are characterized by high power and large inertia, and are widely used in industrial frequency conversion. The cascaded H-bridge multilevel (CHB-ML) inverter adopts a modular design concept to realize high-voltage and high-power functions by cascading multiple identical low-voltage conversion units.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
