A recursive method that eliminates $n+1$ harmonics and their respective multiples from the output voltage of a cascaded H-bridge (CHB) multilevel inverters with notation="LaTeX">$s=2^{n}$ dc sources notation="LaTeX">$(n=1,2,3,\ldots)$...

The Selective Harmonic Elimination (SHE) technique is the fundamental switching frequency scheme which is used to eliminate specific order harmonics. In this paper, the elimination of low order harmonics in cascaded multilevel inverter with equal DC sources is proposed. The modulation strategy used here is SHEPWM in which non linear equations that characterize the low order harmonics are obtain...

Selective Harmonics Elimination is a high-efficiency modulation method for multilevel inverters that allows handling very high voltage applications. It eliminates the most significant harmonics and fixes desired fundamental component. The main issue of these techniques complex process to obtain appropriate switching-angles, being necessary calculate them offline, meaning if some disturbances oc...

Economic benefits from using power electronics equipment are much more visible than losses caused by harmonics produced by this equipment. Consequently, we enter the New Millenium with sources of harmonic distortion more and more distributed over distribution systems. We have to confess that we are much more effective in generating harmonics than in their elimination. This situation should not ...
