Extension of real time harmonic elimination theory to the traditional selective harmonic elimination
2016 8th International Conference on Modelling, Identification and Control (ICMIC), 2016Generally speaking, almost the existing method used to implement the selective harmonic elimination in real time based on look-up table, which will consume lots of memories of the embedded processor. This paper propose a method that extends the real time harmonic elimination strategy based in modified carrier signal theory to the results obtained by ...

Simulation of surplus harmonics in selective harmonic elimination technique
2016 IEEE International Conference on Mechatronics and Automation, 2016Selective harmonic elimination technique can eliminate any order harmonics theoretically, but it is restricted by the initial value of switching angles and the switching speed of power device, therefore, it has surplus high-order harmonics. The surplus harmonics exist in the form of harmonics group, there is a window which harmonic wave amplitude close

General Mathematical Solution for Selective Harmonic Elimination
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020This article proposes a general mathematical solution for a selective harmonic elimination (SHE) technique. The proposed procedure is valid for both symmetrical and unsymmetrical multilevel inverter (MLI) inverter configurations with a wide range of modulation indexes (mi).

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 ...

Selective harmonic elimination in a conventional inverter
2017 8th Annual Industrial Automation and Electromechanical Engineering Conference (IEMECON), 2017Ordinary single phase inverter gives a square wave output which when applied to electrical appliances may damage the later, reduce its efficiency as well as life as this inverter output waveform is not sinusoidal and contains lower and higher order harmonics in addition to fundamental. Moreover, the output voltage cannot be controlled.
