Unified Selective Harmonic Elimination for Multilevel Converters
IEEE Transactions on Power Electronics, 2017 For multilevel converters, as their selective harmonic elimination (SHE) equations are highly related to the switching patterns, it is almost impossible to give a complete study for all the switching patterns under the traditional SHE framework.
