摘要：In order to achieve the sinusoidal control of input current of 3-2 MC (three-phase to two-phase Matrix Converter), the functional expression of two-phase output voltage modulation is formulated. A simplified sector partition method is proposed under the three-terminal topology. The sector partition principle could improve the original space vector modulation strategy, in which the expression of duty cycle is obtained, and the switching function matrix of the modulation strategy is presented. Also, detailed output voltage utilization ratio is analyzed to provide satisfying dynamic response, a dual-closed-loop control strategy based on weighted synthesis feedback of output current is proposed, where the 3-2 MC signal model in dq coordinate system is formulated. The correctness of the theoretical analysis and the validity of the proposed control strategy are verified by experimental results. © 2018, Electric Power Automation Equipment Press.
