A Dynamic Capacitive Power Transfer System for the Elevator

Overview

An innovative system enabling real-time, wireless and efficient power transfer for peripheral electrical systems in elevators and other tracked systems in motion. This technology comprises a metal track attached to the building side as a power transmitter, and a piece of metal on the elevator side as a power receiver. Through a gap between the transmitter and receiver, power can be wirelessly transferred in real-time to power peripheral systems such as control panels, air conditioners, lighting, and other electronic devices within the moving elevator. It uses the elevator's existing steel wheels and ropes to ground the moving car, eliminating the need for electrical cables and a flexible cable carrier system. The system design can be adapted to other vehicles traveling on track systems, such as trains, trolleys, and other vehicles operating on tracks.
