中文摘要:

针对传统的三电平空间矢量脉宽调制(SVPWM)算法运算量较大、实时性差的缺点,提出一种基于参考电压旋转统一处理的简化SVPWM算法,并将其应用到三电平间接矩阵变换器(TLIMC)上。该简化方法通过判断输出参考电压的大扇区并旋转统一到第一扇区,然后判断小三角区,并对矢量的作用时间计算进行归纳优化,使程序运算量减小到原来的1/6,有利于数字信号处理器的程序编程。最终构建了Matlab/Simulink的TLIMC的仿真模型,仿真结果证明了简化策略的可行性。

英文摘要:

According to the disadvantages of the traditional three-level apace vector pulse width modulation (SVPWM) algorithm with a large amount of computation and poor real time, A simplified SVPWM algorithm based on rotation and unified processing of reference voltage is proposed, and it is applied to the three level indirect matrix converter (TLIMC). The method by judging the big sector of the output reference voltage and unify rotation to the first sector, then judge the small triangle area, and optimize the function time of the vector to reduce the amount of computation to the original 1/6, more suitable for digital signal processor program. Finally, the TLIMC simulation model of Matlab/Simulink is constructed, The simulation results prove the feasibility of the simplified method.
