Induction motor supplied from voltage sourced inverter from the view of voltage drop on the input side of converter

This paper solves problems of influence and immunity from the voltage drop of the power supply to the electric drive. There are reflected opportune control algorithms for the quickly to change of working regime from full load in regime “drive” to “no-load” regime and opportune control algorithms for quickly to return to original working. There are also referenced the variants of adaptation of power circuits.
