Harmonic Distortion of the AC Power Line

turbances on the AC power line due to the way the drive draws AC current. Current cannot flow from the rectifier into the DC bus until the input voltage is greater than the DC bus voltage. As shown in figure 3, this only happens for a very short period of time for each phase. This causes a non‐sinusoidal current flow created by the input stage of the drive… (More)
