| 摘 要： | 以应用于高压变频装置的三电平逆变器为特定的研究对象,对特定消谐(Selective Harmonic Elimination Pulse Width Modulation,SHEPWM)技术的求解与应用进行了分析和研究。针对用数值算法求解SHEPWM非线性方程组时初值选择困难的情况,提出一种新的求解方程组。建立了NPC逆变器SHEPWM方法的数学模型,着重介绍了同伦算法的基本思想、模型构造以及求解方法,最后对用同伦算法计算的NPC逆变器模型的结果进行了仿真和实验研究,研究结果证明了SHEPWM和同伦算法的可行性。

| Abstract: | This paper constitutes the mathematical model of the Selective Harmonic Elimination(SHE) technology based on NPC inverter, presents emphatically the thought, model and the solving method of Homotopy Algorithm. The in-vestigations of simulation with PSIM 6.0 and experiment verify that the SHE-PWM and homotopy algorithm are practical. |
