Current model predictive control for a grid-connected four-leg voltage source converter application is presented in this paper. The solution of the optimum criterion defined by predictive control is considered as the reference current. This current will be applied based on projections of the different current control vectors corresponding to the switches states. Geometrical properties of the predicted...
Distributed power systems are getting more attention now-a-days due to their high flexibility and reliability. In this paper, predictive current control strategy is proposed for the grid-connected four-leg inverters. This kind of converter is developed to deliver power to the unbalanced/nonlinear three-phase loads and as well to the grid. The discrete-time model of the converter and load is used to...
This paper presents a control scheme applied to the Direct Matrix Converter (DMC), which combines the advantages of the predictive control and active damping to reduce the resonance of the input filter. A discrete-time model of the converter and the load is used to predict the behavior of the input reactive power in the supply side and the output currents for each valid commutation state. The approach...
