摘要
从反变换的角度对磁链追踪PWM法中的谐波情况进行了分析。推导了定子磁链多边形的径向误差△R、相位误差△φ与谐波的分布以及各次谐波含量之间的关系,并通过仿真研究了径向误差△φ和相位误差△φ对谐波影响的特点。
The harmonics in flux trajectory PWM is analyzed in view of inverse transformation. The relationship between the amplitude and frequency spectrum of the harmonics and the radius and the phase error is derived. At last the effect of radius and phase on the amplitude and the frequency spectrum of the harmonics is studied through simulation.
