Abstract
Elevator installations with electric drive systems are equipped with devices (10) to reduce the power supply connection rating which have energy storage units (11) which are formed entirely or partly from so-called supercapacitors (13). The device (10) according to the invention has the effect on the one hand that power peaks during starting and braking operations are compensated by the exchange of energy between the storage unit (11) and motor supply, and on the other hand that the power consumption occurring during a trip is also spread over a part of the at-rest time. Supercapacitors (13) as energy stores tolerate by comparison with electrochemically acting accumulators a much higher number of charging and discharging cycles at high values of current.
