Is it difficult to change three-level VSC into two-level VSC in this model? From the simulation results, , is there a big difference between two-level and three-level VSC

VSC Based HVDC transmission system (detailed model). On the basis of this model, if I want to change 3-level bridge IGBT to 2-level bridge IGBT, will there be many changes？

Thanks a lot

To use a two level converter you'll need to remove the neutral controller and to change the modulation technique to use a PWM Generator (Three-Phase, Two-Level).

can some body please share 2-level vsc based HVDC model,
