Abstract
This paper presents a new predictive current control (PCC) method to achieve the coordinate control of current and power of the matrix converter under unbalanced input voltages. In order to avoid the complicated input voltage positive-negative sequence extraction, the flexible source current reference is constructed by filtering the square of input voltage vector with a notch filter. The optimal switching configuration to adjust source and load currents is selected by minimizating the cost function which is obtained from the sum of the absolute errors between the current references and their predictive values. Simulation results are given to validate the effectiveness of the proposed PCC method.
