Model Predictive Control of DMC based SST

This paper proposed the Model Predictive Control (MPC) for Direct Matrix Converter (DMC) based Solid State Transformer (SST). The proposed system consists of a DMC based SST feeding to a RL load through a three phase source with input and output low pass filters. The model predictive current control scheme is used for generation of switching pulses for DMC based SST. In MPC, the desired performance of the system is represented through a cost function. The cost function is minimized for finding the sequence of next actuations like an optimization problem. The aim of the MPC is to reduce distortions of input currents with high quality output voltage at unity input power factor operation. To validate the performances of the proposed scheme, simulation have been performed using MATLAB/Simulink platform.
