Hi everybody, im new at this forum, sorry for my english, ive been trying to find information about how to generate the patters to commutate a asymmetric cascaded 7 level inverter exponent two and implement it in the PSIM software with modulation strategy based on carriers and a reference, since the inverter has to generate 7 levels it need 6 carriers, thats true for a simmetric cascaded multilevel inverter, for an ACMLI do i need six carriers too?...i don´t understan exactly the relationship between switching states and the reference signal compared with the carriers based on levels....

weel, how can i simulate an asymmetric cascaded 7 level inverter in PSIM software?? has someone simulated that configuration?

again sorry for my english...jejej

thanks a lot...
