A predictive control strategy for a single-phase AC-AC converter

This paper presents a predictive control strategy to control the load current in a single-phase AC-AC converter. The proposed technique consists on a prediction estimation to choose the available switching state of the converter to be applied one step ahead. By considering a cost function, the best switching state to be applied into the converter the next sampling period is selected. All this is done with the objective to obtain a good performance of the load currents. The proposal is verified by both simulation and experimental results, which show a very good dynamic and stationary performance.
