Hello friends! Today, we will study an 11-level, three-phase cascaded H-bridge inverter in MATLAB and Simulink. We will begin with one H-bridge cell, connect five cells in series to form a phase, and then combine three phase assemblies. This approach makes the voltage levels easier to understand than starting with a large diagram full of switching signals. The original project illustrates the overall arrangement and retains useful phase and line-voltage plots. We will keep those images while correcting the distinction between gate signals and power sources, the switching requirements for eleven levels, and the meaning of the older switch-model parameters. These details determine whether a simulation represents the intended converter. Our emphasis is a transparent simulation model. We will ...
