International Journal of Electrical Engineering & Education, 1982
A review of the techniques presently available for the control of harmonic content in three-phase a.c.-d.c. convertors is presented. It includes increased pulse numbers, harmonic filters and harmonic injection. Recent trends and main problem areas encountered in filter design are given special consideration.

Harmonic elimination switching through modulation
2004 IEEE Workshop on Computers in Power Electronics, 2004. Proceedings., 2006Harmonic 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 Comprehensive Review of Solving Selective Harmonic Elimination Problem With Algebraic Algorithms
IEEE transactions on power electronicsSelective harmonic elimination pulsewidth modulation (SHEPWM) is an effective way to eliminate low-order harmonics in high-power applications. However, one of the biggest challenges of SHEPWM is to solve the selective harmonic elimination (SHE) equations,
