Please I need some help, I'm trying to simulate a MMC with 5 cells per arm dual half bridge submodels. I get the Cyclic behavior during switching error, I have tried all solutions listed in forum and help guides no luck at all, I checked the modulation scheme is correct by checking the output voltage of each arm when it's isolated and it works well, I did check PWM harness and it generate the expected voltage wave form , but when I connect ARMs together through a mutual winding and to the DC source I get this error.
I tired to model that in simulink using PLECs blockset but with fewer 2 cells per arm it work just fine, but would like to stick with PLECS standalone,
I know multiple questions about the same issue but any help is highly appreciated. attached PLECS file
any help is appreciated,
