Optimización evolutiva del contenido armónico de un inversor

Luis D Pabón F., Jorge L Díaz R, Aldo Pardo G

Resumen


Este artículo trata sobre la optimización distorsión armónica total (THD) de un convertidor multinivel trifásico con fuentes independientes. Mediante la programación de un algoritmo genético que localice el punto de menor distorsión armónica. Como función objetivo se toma el THD de la tensión de fase, en

términos de los ángulos de conmutación en la modulación. De esta manera el problema se resuelve mediante un enfoque netamente numérico y evitando los problemas asociados a las técnicas de modulación convencionales que utilizan comparaciones con ondas portadoras para obtener una modulación. Los resultados de la optimización fueron probados y validados mediante simulación.
