Abstract

This paper deals with the design of a source for the selective generation of harmonics, aimed at deepening the analysis of one of the main phenomena affecting power quality in electrical systems. As a first step, the pertinent equations were developed through frequency-domain analysis using Fourier theory. A general equation was obtained as a function of harmonics, switching angles, and voltage levels, taking as a reference the topology of an 81-level asymmetric multilevel converter. With these equations, it is possible to determine the switching angles necessary for the controlled generation of the desired harmonic over the fundamental waveform.
