Research output: Contribution to journalConference articlepeer-review


Harmonic elimination methods create discrete-valued switching control waveforms with explicit harmonic content A major drawback is that these methods do not allow dynamic adjustment as frequencies and amplitudes change continuously. Harmonic elimination is constructed in a general manner here, leading to infinite numbers of solutions. A modified carrier approach that closely approximates the performance of harmonic elimination is introduced. The modified approach can produce even lower weighted total harmonic distortion than conventional harmonic elimination, and supports dynamic PWM with low harmonics.
