Resumen:
Multilevel
inverters are widely used in solar energy generation systems consist of various
photovoltaic generators. These converters deliver distorted output waveforms.
There are trascendental equations characterizing the harmonic content but the
degree of the polynomial increases with the number of DC sources or the number
of harmonics to be eliminated. Also, the solutions are discontinuous in some
points. In this paper, a way is proposed to minimize the output harmonics of a
multilevel inverter. The Particle Swarm Optimization algorithm used to minimize
the Total Harmonic Distortion, subject to restrictions on the harmonic content
allowed. The appropriate switching angles can be calculated to mitigate the harmonics.
The proposed method has been succesfully applied to a cascaded multilevel
converter of seven levels. This method can be extended to more levels
inverters.
