Optimal Time Five Voltage Vector Finite-set Model Predictive Control

In this paper, the five space vector modulation method is adopted on the basis of the traditional finite-control-set model predictive control, which can effectively to reduce the common mode voltage, and suppress the switching losses. The delay compensation is added to the finite-control-set model predictive control to construct the cost function of reducing the deviation from the output current, and calculate the optimal action time of the five vectors. The experiment verifies that the optimal time five voltage vector finite-set model predictive control effectively dropped down the common-mode voltage, improved the symmetry of the three-phase output current and the waveform quality.
