With 3-phase motor drives using SCR 6-pulse (6-diode) rectifiers, there are short intervals of time when more than one SCR is ON. This causes a transient short circuit to flow six times per line power cycle. This short circuit current flow causes nonlinear voltage to drop across the system impedance and results in distortion in the voltage waveform called a notch.
