Abstract：Aiming at the low voltage transfer ratio shortage of two-stage matrix converter (TSMC), on the basis of over-modulation strategy of current and voltage source converter, a space vector over-modulation algorithm suitable for rectifier and inverter of TSMC is proposed respectively, which improves the maximum voltage transfer ratio from 0.866 to 1.053 and controls the output voltage fundamental amplitude linearly as well as owns the low total harmonic distortion. Moreover, the inverter modulation strategy with this over-modulation algorithm can effectively immune to the influence imposed on the output performance caused by surge and sag input voltages. In addition, the algorithm are neither necessary to store a lot of data nor to do complex calculation, which are very suitable for implement. The feasibility and validity of the proposed over-modulation strategy are verified by simulation and experiment.
