you should mention the application of this converter. inverter or rectifier?if you give me an email at this address [email protected] I can send you some papers on simulation of multilevel inverters
nice discussions for beginners, experienced who wants to see what others do. Hani Vahedi, I will send you email for those papers on multilevel inverters, because I want to start new research.
