Power quality problems are associated, among other things, with the reactive power generated at the AC side in distribution systems. In this regard, the three-phase distribution static compensator is becoming a viable alternative in order to achieve reactive power compensation or in other words to obtain a unity power factor. This paper introduces the experimental validation of the distribution static compensator based on a 7-level cascade H-Bridge converter. The experimental test bench is based on the silicon carbide metal-oxide-semiconductor field-effect transistor devices. The results are obtained by using a fixed switching frequency model-based predictive controller based on a pulse-width modulation strategy. The proposed design is implemented to mitigate power quality issues induced by reactive load and experimental results are provided to show the performance of the proposed controller.
