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.

This paper describes the design and field application of a high-efficiency single-phase AC/DC converter that is suitable for distribution lines. First, an appropriate AC/DC converter was designed in consideration of the environment of the application system. In order to ensure high efficiency and high reliability, we designed an optimum switching element and capacitor suitable for the converter, and the protection element of the AC/DC converter was designed based on these elements. The control function for the power converter suitable for an LVDC distribution system is proposed for highly reliable operation. The AC/DC converter was manufactured based on the design and its performance was verified during application in an actual low-voltage DC (LVDC) distribution grid through tests at the demonstration site. The application to a DC distribution system in an actual grid is very rare and it is expected that it will contribute to the expansion of LVDC distribution.
