6/5/2016 The Regenerative Braking System KONE was the first company to make regeneration available in the elevator industry in the early 1990's. It was invented in Finland by KONE together with Tampere University. No need for external devices to accept regenerated energy: The Modulated Line Bridge (MLB, encircled) will automatically adjust:  Frequency  Phase and  Voltage. How regenerated energy is returned 23 6/5/2016 © KONE Corporation | KONE Eco-efficient™ solutions

Regeneration requires sufficient load Most countries do not accept energy to be returned to the external building grid.  Regenerated energy must therefore not leave the building, but must be re-used within the building by other loads (Lighting, Airconditioning, other elevators, etc).  Make sure that there is enough load on the elevator grid to consume the regenerated energy.  If the unusual case that there is not enough load, braking resistors must be used to minimize regenerated energy. 24 6/5/2016 © KONE Corporation | KONE Eco-efficient™ solutions
