“…En contraste, la técnica MPC a frecuencia de conmutación fija, consiste en elegir dos vectores óptimos para ser aplicados en ciclos de tiempos determinados por sus factor de ponderación en la función de costo, junto con uno de los vectores ceros, en cada instante de muestreo [6]. Varios son los trabajos encontrados en la literatura que han estudiado esta problemática recientemente [7], [8], [9], en los cuales se han reportado mejoras en términos de la distorsión armónica total (THD) para el control de corriente, par mecánico, control de potencia reactiva y activa, flujo electromagnético, entre otros aportes [10]. El aporte del artículo, es la comparación entre la aplicación del control MPC clásico y el de a frecuencia fija, aplicado a un convertidor matricial monofásico.…”

This paper considers some of the aspects of applying predictive control to a single phase Matrix Converter. Among all the proposed control techniques for Matrix Converters, predictive control has become a plausible and versatile option due to its ability to deal with different system and operation requirements. The main problem with predictive control is that it generates a variable switching frequency for each power device, creating an imbalance in the losses and therefore potentially their useful life. This variable switching can also cause a high harmonic content in the output waveforms of a matrix converter. This work proposes to implement the predictive control technique with a fixed switching frequency applied to the single-phase matrix converter (SPMC) and a comparison of the performance between the proposed control and the variable switching frequency counterpart, showing the advantages and disadvantages between the two strategies.
