A control strategy for a matrix converter based on Venturini method under unbalanced input voltage conditions

In this paper, a control strategy based on Venturini method is presents in order to solve the impacts of unbalanced input voltage conditions on the matrix converter performances. Conceptually, this strategy is done by modifying the mathematical model for controlling the modulating waves to satisfy the desirable feature, as generated in the event of normal situation. Up to this approach, it can support either single-phase condition or two-phase condition. Performance of the proposed control strategy was verified by the simplified simulation model in the MATLAB/Simulink software. It is clearly shown that the matrix converter can be controlled for regulating the balanced output voltages with showing good steady-state and dynamic operations without the energy storage devices.
