Elevator Regenerative Energy Feedback Technology

Abstract

Elevator regenerative energy feedback technology is an important method of reducing energy consumption. Elevator regenerative energy feedback technology includes energy feedback system structures and feedback energy storage methods. This article introduces the feedback system structures and energy storage methods. The dual PWM regenerative energy feedback circuitry and plug-in regenerative energy feedback system are analyzed, and their different characteristics are concluded; the battery and the supercapacitor energy storage methods are discussed and the novel technology on the energy storage is described. This paper aims to introduce different structures and storage methods to help deepen the further understanding on the elevator energy feedback technology.
