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. Current documentation associated with Don's research can be found here. Don's fast and precise calculator of pulse solutions, the results of which I have compared to and refined my efforts, can be found here.
