Abstract The research purpose of the authors is reducing the energy consumption of the main worldwide consumer - the electric motors- by useful utilization of the input energy through the Regenerative Electric Drive System having also the power quality features. The prototype of the electric elevator consists mainly of two trolley: one serve for the active load, and the other as counterweight, gearbox, power converter, induction machine and chain transmission. The elevator is driven by using 4kW three-phase induction machine through AC-AC power converter and has the capacity of 450 kg. The numerical simulation results and the experimental platform are shown.
