Abstract：In this paper, the analytical expression of grid side power factor based on establishment of the mathematical model of two stage matrix converter is yielded. It is focused on the influences of system parameters on the grid side power factor, which draws the conclusion that the adjustable range of grid side power factor of 18 switches TSMC depends on the system parameters. Simulation examples are given to illustrate the correctness of the conclusion. To deal with the problem of non-unity power factor, a new control method of grid side power factor is presented, which realizes closed-loop control and achieves dynamic compensation of grid side power factor. This new control method ensures the grid side power factor maintains unity power factor while the system parameters change. Experimental results demonstrate the feasibility and validity of this method.
