Performance characteristics of a cascaded two-level converter

A cascaded two-level converter is proposed which utilizes two six-transisto r inverters and is capable of producing voltages which are identical to tho se of three-level and four-level converters. Since the machine voltages are the same, the converter performance iii the same as is verified through la boratory tests. The advantages and disadvantages of tie proposed cascaded c onverter are explored. The proposed converter is simpler to construct and o ffers more non-redundant switching states per number of active semiconducto rs than standard multi-level converters.
