REGENERATIVE ENERGY STORAGE DEVICE OF ELEVATOR SYSTEM

摘要

PURPOSE: A regenerative energy storage device for an elevator system is provided to store regenerative energy generated when an elevator car lifts up and down and to reduce power consumption by using the regenerative energy as driving power. CONSTITUTION: A regenerative energy storage device for an elevator system comprises a regenerating part(100). The regenerating part stores the regenerative power generated by an electric motor of the elevator system and comprises a charging and discharging part(120) and an energy storage part(110). The charging and discharging part is electrically connected between an inverter and a DC link of the elevator system. The energy storage part is electrically connected to the charging and discharging part.
