摘　　要：针对三电平逆变器调制算法在调制中会出现窄脉冲的问题,在分析了归一化扇区三电平空间矢量脉宽调制(SVPWM)算法的基础上,研究了此调制方法窄脉冲产生的原因及影响,提出了归一化扇区三电平SVPWM算法的窄脉冲抑制算法。通过理论推导证明了提出的方法的可行性,方法不仅能够抑制窄脉冲的出现,同时也实现了补偿。通过MATLAB/SIMULINK仿真结果证明了提出算法的正确性。Aiming at narrow pulse problem occurs in modulation of three-level inverter modulation algorithm,on the basis of analyzing normalized sector three-level space vector pulse width modulation (SVPWM)algorithm, generation causes and effects of narrow pulse of this modulation method are researched,a narrow pulse suppression algorithm based on normalized sector three-level SVPWM algorithm.The feasibility of the method is proved by theoretical deduction.This method can not only restrain occurrence of narrow pulses,but also realize compensation.Correctness of the algorithm is proved by the simulation results of MATLAB/SIMULINK.
