摘要
根据常见变频器调制方式下的谐波特性,并基于 RLC 滤波器的高低频等效电路,提出了一种合理选择正弦滤波器参数,有效提高变频器输出正弦波质量,降低高次谐波的方法。
According to resonance characteristic of conventional frequency converter in the modulation mode and the RLC Filter's high and low frequency con verter circuit,a method is introduced reasonably choose the pa- rameters of the sinusoidal filter and effectively improve the quality of the sinusoidal wave of the frequency con- verter and decrease higher harmonic wave.
