Multilevel Selective Harmonic Elimination for an Asymmetric Converter
2018 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2018A novel Multilevel Selective Harmonic Elimination technique is presented for a 27-Level cascaded converter that follows the 9:3:1 ratio. The mathematical model of the AC waveform in the frequency domain allows to calculate the firing angles of the power cells in order to eliminate all the non-triple odd harmonics below the 51th order.

Selective Harmonic Elimination for an Asymmetrical Multilevel Converter
2007 IEEE International Symposium on Industrial Electronics, 2007In this paper, a novel asymmetrical multilevel converter is proposed which is composed a 3-level leg and a 2-level leg. The principle of the converter is analyzed. The new schema requires fixed insulated supplies instead of capacitors. Selective harmonic elimination method is used to eliminate the specified harmonics in the output voltage.

Selective Harmonic Elimination PWM For a Cascaded Multi-level Inverter
2020 IEEE International Conference on Industrial Technology (ICIT), 2020This paper deals with the selective harmonic elimination pulse width modulation (SHE-PWM) technique. This technique is used for the elimination of selected dominant low order harmonics in the multi-level inverter output voltage. The presence of these harmonics is the essential drawback of such kind of inverters; especially when it is used for the ...

Selective harmonic elimination for the modular multilevel converter
2016 North American Power Symposium (NAPS), 2016This paper will analyze the power quality of multilevel voltage waveforms generated using three modulation strategies: i) a conventional nearest level control (NLC) strategy, ii) NLC with harmonic elimination, and iii) optimized selective harmonic elimination (OSHE).

Elimination of selective harmonics in a Multi-Level Inverter
2013 7th International Conference on Intelligent Systems and Control (ISCO), 2013This paper presents a selective harmonics elimination in Multi-Level Inverter. The basic concept of this reduction is to eliminate specific harmonics, which are generally of the lowest orders, with an appropriate choice of switching angles. This paper employs Homotopy algorithm to solve the transcendental equations for finding the switching angles ...

An Improved Modulation of the Selective Harmonic Elimination Controlling
2006 International Conference on Power System Technology, 2006In the application of the traditional selective harmonic elimination technique, the lowest un-eliminated harmonic and the total harmonic distortion factor are obviously enlarged usually, which would do great harm to the power system. In order to solve the problem, this paper presented an improved harmonic elimination technique. In this new technique, a

Selective Harmonic Elimination for medium voltage drives
2022This technical note explores the implementation and performance evaluation of Selective Harmonic Elimination (SHE) using a Programmed Patterns PWM (PP-PWM) modulator. Designed primarily for high-power applications operating at low switching frequencies, SHE lowers current harmonic distortion to relax physical filtering constraints.
