In the context of PV power plants, the "high-power" classification for multilevel inverters usually applies to systems operating in the MW range, incorporating medium voltage levels of 2.3–13.8 kV to optimize energy transmission efficiency and support reliable system performance .
The proposed inverter is a resultant structure of a number of integrated module and each module is configured with a number of series connected basic blocks. Each block consists of a dc voltage source, a blocking diode and a semiconductor switch.
A high-voltage full bridge inverter works by converting the DC voltage V1 to a high-frequency square wave AC voltage. This AC voltage is then supplied to a 20kHz frequency high-voltage transformer T1, which, after the boost rectifier, provides power to the load. The inverter high-voltage full bridge drives the routing components and the IGBT power modules.
The elementary concept of a multilevel inverter to achieve higher power is to use a series of power semiconductor switches with several low voltage dc sources to perform the power conversion by synthesizing a staircase voltage waveform.
