The Application Three-phase to Single-phase Z-Source Matrix Converter in Wind Turbine
Journal Title: روش های هوشمند در صنعت برق - Year 2016, Vol 7, Issue 28
Abstract
In this paper a new idea of direct three-phase to single-phase Z-source matrix converter (impedance-source matrix converter) applicable in stand-alone wind turbine is introduced. In the direct Z-source matrix converter amplitude of output voltage and frequency regulation are of importance to control system. In wind turbines, input voltage and frequency are usually changing due to wind speed variation that these alterations could be easily regulated by means of a direct Z-source matrix converter. A scheme is also offered to control the proposed direct three-phase to single-phase Z-source matrix converter. the control strategy would be able to adjust the output voltage and frequency at desired value as well as producing low THD (total harmonic distortion) at the output voltage. The proposed structure and the control methodology are simulated using matlab simulink software and results are investigated and discussed to confirm the performance of the direct Z-source matrix converter in wind turbine.
