Voltage unbalance or sag conditions generated by the line excitation can cause the input rectifier stage of an adjustable-speed drive (ASD) to enter single-phase rectifier operation. This degradation of the input power quality can have a significant negative impact on the induction machine performance characteristics. This paper provides an approximate closed-form analysis of the impact of line voltage sags and unbalance on the induction machine phase voltages, currents, and torque pulsations… CONTINUE READING
