A Predictive Control with Dual Input and Dual Output Indirect Matrix Converter

Based on the traditional indirect matrix converter topology dual input dual output indirect matrix converter is proposed, but the conventional six-switch inverter, used in the singleoutput indirect matrix converter, is replaced by a nineswitch dual output converter. The matrix converter has several advantages over traditional rectifier-inverter type power frequency converters. It provides sinusoidal input and output waveforms, with minimal higher order harmonics and no sub harmonics. Model Predictive Control (MPC) uses the discrete-time model of the system to predict future value of the controlled variable for all possible control actions and user-defined cost function related to control objectives is solved to find its minimum. The matrix converter providing directly AC-AC power conversion is one of the most interesting members of the power converter family. The control action which minimizes the cost function is selected and applied to the system for the next time interval. This paper presents a finite control set model predictive control strategy for a dual-input dual-output indirect matrix converter.
