Why do I see huge voltage spikes at the output of a 3 phase MMC (Modular multi-level converter) in Simscape, when the number of submodules >1, but not with 1 submodule?
The model may be a bit challenging for the solver due to parameterization. In this case, one way to avoid these spikes is to swi...
