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.
What is a high power switch in an inverter?
The high-power switches are the most critical component in the inverter as they control the flow of current to the motor to generate motion. As such, the switches' are monitored and protected by sensing their temperature, voltage and current throughout their operation.
What are the applications of control systems in high-power inverters?
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.
Why should you choose a high-power inverter?
In addition to the mentioned features, high-power inverters provide advanced monitoring and control capabilities. This feature allows operators to remotely monitor power plant performance, troubleshoot system errors more quickly, and perform necessary repair and maintenance tasks with minimal cost and waste of time and energy, if needed.
