Abstract
En 中文
To increase the voltage transfer ratio of the matrix converter and improve the input/output current performance simultaneously, an over-modulationmethod based on predictive control is proposed in this paper, where the weighting factor is selected by an automatic adjusting mechanism, which is able to further enhance the system performance promptly. This method has advantages like the maximum voltage transfer ratio can reach 0.987 in the experiments; the total harmonic distortion of the input and output current are reduced, and the losses in the matrix converter are decreased. Moreover, the specific implementation of the proposed approach is developed in detail. Simulations and experiments verify the effectiveness of the proposed method.
