Abstract

In a method and apparatus for reducing power loss in devices for contactless data and energy transfer, a function unit is provided in a movable part which ascertains the value of the current loss of a voltage regulator. This value is then either stored in memory or compared with a command value. A stationary part can read out this value or receive a signal if the command value is exceeded, which indicates to it that the energy supply must be reduced.
