Abstract
A system for contactless energy transmission includes a transformer formed by a primary winding and a secondary winding, which transformer is designed so as to be resonant as a result of capacitors. By measuring and comparing electrical state variables on the primary side and on the secondary side the efficiency of the transmission of electrical power from the primary side to the secondary side is determined, and by varying the resonance frequency of the transformer or of the frequency of a primary voltage applied to the primary winding the resonance frequency and the primary voltage frequency are attuned to each other.
