摘要 本文提出了一种优化空间矢量脉宽调制方法来抑制光伏并网逆变器中产生的共模电压。在分析共模电压产生机理的基础上,对通常SVPWM调制技术进行改进,调整了有效矢量的选择范围,并对开关次序进行优化。该空间矢量合成算法克服了SPWM调制存在的母线电压利用率低,线性调制区小的问题。仿真结果表明,该算法可以将共模电压幅值抑制到普通SVPWM算法的1/2,具有良好的有效性和实用性。 In this paper,an optimization SVPWM method is used to restrain the common-mode voltage generated in grid-connected PV inverters.Based on the analysis of the generated mechanism of the common-mode voltage,the normal SVPWM modulation technology is improved by adjusting the range of choose effective vector and optimizing the switching order.The simulation results show this algorithm can suppress common-mode voltage amplitude low to 1/2 of the general SVPWM algorithm.
