摘要
通过对PWM型变频器输出波形的数学模型进行分析 ,采用数值法计算出可消除m个由低到高奇次谐波的触发角系列 ,并对数值法计算结果进行仿真研究 。
By an analysis of mathematic model of output waveform generated by PWM converter,numerical method is used for calculating the series of trigger angles which can eliminate m odd harmonics from low order to high order.And results of value calculation are studied by simulation method.It is shown that the harmonic suppression technique is effective.
