An Advanced Gate Driver for a High-Power Inverter based on Hybrid Switch SiC+IGBT technology
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.
In addition to LS-PV-PPs, high-power inverters are used in various applications, including large electric motors, Flexible AC Transmission Systems (FACTS) devices and renewable energy (RE) converters .
However, its dependency on precise system modeling might bring instability in the presence of parameter variations or unmodeled dynamics . One of the application of control systems in high-power inverters is to increase the speed and accuracy in achieving MPPT.
In order to attain elevated output power levels, obviate the necessity for low-frequency transformers, generate multilevel output voltage, and implement distributed MPPT, a novel three-phase topology has been introduced in Ref. tailored for CHB-based inverters.
