摘要 本文以减少转矩脉动为目标 ,优化出改进梯形波变化因子的最佳值 ,建立了改进梯形脉宽调制 (MTPWM)逆变器供电异步电动机计及主磁路饱和时的变频调速系统数学模型 ,仿真结果表明 :MTPWM模式在提高馈电给逆变器的直流电压利用率同时 。 Changeable factor optimum values of modified trapezoidal wave are optimized,with the aim of reducing torque ripple,the mathematical model of induction motor variable frequency variable speed system fed by modified trapezoidal pulse width modulated (MTPWM) inverter is set up,allowing for the effect of main magnetic circuit saturation,and the simulation results indicate: MTPWM pattern reduces the torque ripple as well as achieving the effective utilization of the DC supply voltage for the inverter.
