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 ...

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

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 ...

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.
