讨论了基于双电压瞬时值控制的矩阵变换器的开关状态及控制函数,系统地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该控制策略下输出电压的合成规律。最后通过仿真和实验结果分析,给出了电压、电流的波形,验证了该控制策略具有良好的抗干扰性能。

The switch state and control function of Matrix Converters based on double voltage instantaneous value control are discussed. The control function of matrix converters based on double voltage control strategy under unbalanced in- put is analyzed. Finally, the simulation and experiments results of voltage and current waveform are given, which verify the correctness of its theoretical analysis. And that will provide a theoretical basis for the design and realization of matrix converter.
