Abstract
A system for an elevator includes at least one battery and an energy exchanger coupled to the at least one battery and configured to let a DC bus float between a first voltage and a second voltage. An energy storage device is coupled to the energy exchanger. The energy storage device is configured to recapture energy that is not recaptured by the at least one battery during a run of the elevator. The energy storage device is also configured to provide energy to the elevator when demand for energy by the elevator exceeds a threshold.
