Resumen
En este artículo se explora un método para regular las tensiones en los buses de CC en un filtro activo de corriente. El inversor es un convertidor multinivel de cinco niveles y está formado por dos celdas en configuración puente H con enlace capacitivo. Mediante la medición del bus de CC de una celda, se controla la tensión en la otra reduciendo así el número de sensores de tensión. Para llevar a cabo la regulación del bus de CC y la corriente de salida, se utiliza un controlador PI para cada lazo de control. Se presentan una serie de análisis, simulaciones y resultados experimentales del sistema de potencia con el fin de validar la propuesta de este trabajo.
