    • The invention relates to a system for contactless energy transmission to a part of the system, in particular a movably arranged part of the system, and to a method, where a stationarily installed primary conductor is provided to which one or several secondary coils enclosed by said part are inductively coupled. According to the invention, the secondary coils are connected in series with one or several capacitors such that the resonance frequency of the thus formed series resonant circuit is essentially equal to the frequency of an alternating current injected into the primary conductor, wherein the voltage occurring at the series resonant circuit is fed to a rectifier, on the output side of which a switch is provided which can be actuated as a short-circuiter, the current not passing through the switch being fed to a smoothing capacitor via a free-wheeling diode and the voltage occurring at the smoothing capacitor being made available to a user.
