This paper considers the theoretical problem of eliminating harmonics in inverter-output waveforms. Generalized methods are developed for eliminating a fixed number of harmonics in the half-bridge and full-bridge inverter-output waveforms, and solutions are presented for eliminating up to five harmonics.

On the successive elimination of perturbation harmonics
Celestial Mechanics & Dynamical Astronomy, 1993The author presents a method of investigation of perturbations of an integrable Hamiltonian system of two degrees of freedom. He discusses its advantages and defaults in comparison with other applications. The main idea is based on the fact that a Hamiltonian with only one harmonic is integrable.

Harmonic elimination for constrained optimal PWM
30th Annual Conference of IEEE Industrial Electronics Society, 2004. IECON 2004, 2005The selected harmonic elimination (SHE) pulse-width modulation (PWM) inverter eliminates low-order harmonics by optimizing the distribution of switching angles and can generate high quality output waveforms. The goal of optimal SHE-PWM is to select the switching instances (angles) in such a way that a waveform with a particular characteristic is ...

Walsh function method of harmonic elimination
Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002An analytic method for harmonic elimination using the Walsh function harmonic analysis method is proposed. This algorithm simplifies the computation and produces accurate results in order to eliminate selected harmonics. The new algorithm, which also makes online fundamental amplitude modulation feasible, is proposed for general linear time invariant ...

Generalization of Selective Harmonic Control/Elimination
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006Previous work on selective harmonic elimination/control has made fundamental assumptions that enforce output waveform quarter- or half-wave symmetry, presumably in order to reduce the complexity of the resulting equations. However, the quarter- or half-wave symmetric assumption is not required and it restricts the solution space, which can result in ...

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.
