Quasi seven-level operation of multilevel converters with selective harmonic elimination
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Generally, selective harmonic elimination (SHE) complexity for multilevel inverters increases with the increase in number of levels. In this paper, a novel approach for SHE is introduced. This approach is based on cancelling ...
