ELEVATOR SYSTEM WITH DUAL POWER SUPPLY

Modern high-rise buildings require use of a growing number of elevators that have become important factors in energy consumption. Most of the existing lifts are powered from the grid. In order to reduce grid energy consumption and increase reliability, an improved elevator system which uses dual power supply is proposed in this paper. This system supplies electronic modules of the elevator with renewable sources whenever there is sufficient sunlight and maintains usual work of the elevator in case of electricity power failure. The corresponding architecture of the proposed elevator system and needed battery capacity for correct operation are given in this paper
