Magic Sinewave Research

(selective harmonic elimination in three-level PWM)

Robert F. Ackermann (ackrman.net)

Magic Sinewaves, of Don Lancaster (The Guru's Lair), represent an important advancement in the field of harmonic elimination in pulse-generated fundamental waveforms. Magic Sinewave solutions are suitable for a wide range of applications, however, I find them of particular interest for the purpose of efficient solar power AC synthesis and AC motor control. Documentation and calculators associated with Don's research can be found here. My contributions are listed below:
