What is described here is a system for non-contact transmission of electrical energy or electrical signals, respectively, between parts mobile relative to each other, which comprises inductive or capacitive coupler elements which are supplemented by appropriately complementary dummy elements so as to form resonance circuits, and which are supplied by a switching or amplifying element, and wherein said switching or amplifying element is supplemented so as to form a power oscillator. The invention is distinguished by the provision that the resonance circuit employed for transmission is the frequency-determining circuit element and that a signaling means is provided which, on the basis of voltages and currents of said resonant elements, generates a secondary coupling signal for said switching or amplifying element such that oscillation will take place on at least one resonance frequency of said resonance circuits, and that moreover said signaling means is so designed that in the event of a series resonance it couples out a magnitude proportional to one part of a series resonance current, and in the event of a parallel resonance it couples out a magnitude proportional to one part of a parallel resonance voltage.
