为了提高直流母线电压利用率及实现线性调制到过调制最大输出(六阶梯波)的平滑过渡,研究了一种快速计算过调制中控制角的双模式过调制算法,该算法简单、有效,程序执行时间短,能够使系统的调制范围由线性调制区的最大范围(SVPWM)0~90.7%扩展到0~100%,并搭建中点箝位型三电平逆变器实验平台,对该双模式控制策略下的有效性进行了验证。实验结果表明,输出电压明显提高,可以满足多数高转矩输出或较低电压场合的需求,该策略具有实用性的参考价值。

In order to improve the direct current bus voltage utilization and implement the smooth transition from the linear modulation to the maximum output(six-step stage wave) in overmodulation operation,a quick two-mode algorithm of calculating control angle was researched.It simply and effectively implement the scope of modulation range extended from the maximum linear region(SVPWM)0~90.7%to 0~100% and shorten the time of program operating.At last,neutral-point clamped(NPC) three-level inverter exper...
