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 ...

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 ...

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 ...

A new method for harmonic elimination
2011 Annual IEEE India Conference, 2011A new filter strategy for harmonic elimination is introduced in this paper. The proposed approach eliminates all harmonics component from the signal (current or voltage) and it requires only knowledge of fundamental frequency of the signal. The proposed active series filter eliminates undesirable harmonics from periodic signal.

Selective harmonics elimination: PWM method versus optimized total harmonic distortion
4th International Conference on Power Engineering, Energy and Electrical Drives, 2013This paper describes two different PWM methods to improve the quality of the output voltage waveform provided from five level inverter. The first one is the selective harmonics elimination (SHEPWM). The purpose is to cancel the 5th, 7th and 11th harmonic row.

A Complete Solution to the Harmonic Elimination Problem
IEEE Transactions on Power Electronics, 2003The problem of eliminating harmonics in a switching converter is considered. That is, given a desired fundamental output voltage, the problem is to find the switching times (angles) that produce the fundamental while not generating specifically chosen harmonics.
