Predictive Voltage Control of the Direct Matrix Converter applied to Grid Current Injection

Abstract

Predictive control applied to direct matrix converter provide a feasible option to control the output voltage of a generation system with good performance. In this work a predictive voltage control strategy is proposed as the inner loop control of an outer PR current control strategy to inject controlled power to the main distribution grid from an AC generation system. The proposal shows good performance in terms of THD and desired current traking.keywords-predictive voltage control, distributed generation, matrix converter, current control.
