摘　　要：本文分析了当输入不对称或不平衡时,矩阵式变换器的双电压瞬时值控制的原理和在该控制策略下输出电压的合成规律,证明该控制策略具有良好的抗干扰性能;并分析了在非平衡状态下,输入电流的畸变及其消谐方法.最后搭建了与实际电路相近的仿真模型,通过仿真分析,验证了理论分析的正确性,为矩阵式变换器进一步应用研究提供了参考.This paper analyzed the control function of a matrix converter under unbalanced inputs, based on a double line-to-line voltage control strategy. The input current and the harmonic wave reduction are also studied, demonstrating the disturbance-rejection performance achieved by using this control strategy. Simulations are done and current waveforms are recorded and shown in this paper, validating the theoretical analysis. This work may provide a basis for the design and implementation of matrix converters.
