Control Strategy of Three-Phase to Two-Phase Matrix Converter Based on Sinusoidal Input Current
摘要
Abstract
Based on the sinusoidal control of the input current,the constraint relation of the three-phase to two-phase Matrix Converter (3-2MC) output voltage modulation function was derived.According to the conventional space vector modulation strategy,the sector was divided into a large number of sectors.A new type of sector partition method was proposed to reduce to 24 sectors.A new space vector modulation strategy was proposed based on the sector partition.The operating modes of the 3-2MC under the control strategy was analyzed,detailed modulation algorithm was given,got calculation formula of duty ration,and deduced the expression of 3-2MC voltage transfer ratio.Finally,simulation results confirmed the effectiveness and feasibility of the new control method.关键词
