Total harmonic distortion (THD) is usually required to be less than 5% in three-phase AC power supplies generated by means of an inverter, even when supplying nonlinear loads. Through the proposed modulation technique, based on harmonic elimination, it is possible to eliminate the low frequency harmonic content owed to the nonlinear load operation and fulfil THD requirements.
