摘要：This paper proposes the sparse matrix converter as variable speed drives of a direct driven wind energy conversion system (WECs), because its features can provide excellent power quality at both sides of the converter and does not require dc-link energy storage. Variable speed control of the WECS is proposed to get maximum power of the generator on each wind speed variation based on the optimum torque control method. The electromagnetic torque of the generator is regulated using PI controller according to the optimum torque of the wind turbine located at the point of maximum power. The output of PI controller is the reference voltage for modulation of SMC switches based on Space Vector Modulation (SVM) method. The verification result of the proposed model through the simulation shows that the generator output power can reach the maximum point on each wind speed variation. The use of SMC has also been able to improve the power quality with low Total Harmonic Distortion (THD) of voltage and current at grid side.
