摘要:
针对传统的多电平调制策略直流电压利用率低的问题,提出了一种用于级联多电平逆变器(CMI)的载波相移梯形波脉宽调制(CPS-TPWM)策略。在对载波相移技术进行数学分析的基础上,推导了梯形波三角化率σ与CMI输出基波幅值和谐波含量的数学关系。在选取合适的σ值和拥有良好谐波特性的条件下,该调制策略大幅提高了CMI的输出电压基波幅值。在Matlab/Simulink中搭建了三相九电平CMI模型进行仿真验证,仿真结果证明了该方法的正确性和可行性。
Abstract:
For the issue of the low utilization rate of direct current(DC)voltage with the traditional multilevel modulation strategy,a carrier phase shifting trapezoidal pulse width modulation(CPS-TPWM)strategy for the cascaded multilevel inverter(CMI)is proposed here.The relation of the trapezoidal wave triangular factor σ with the fundamental amplitude and the harmonic content of the CMI output is deduced based on the mathematical analysis of the carrier phase shifting technique.By choosing the appropriate σ value and making the CMI process possessing the better harmonic performance,the fundamental amplitude of output voltage is greatly improved by the proposed modulation strategy.A three-phase nine-level CMI model is built by the Matlab/Simulink,and the simulation results verify the correctness and the feasibility of the proposed method.
