Abstract:
A system for non-contacting transmission of electrical power and signals comprising:a first electrical transmitting circuit comprising a switching and amplifying element to form a power oscillator, and a transmitting side of an inductive coupler element, wherein an inductive complementary dummy element is included in the transmitting circuit to supplement the inductive coupler element, to form one resonance circuit which includes the transmitting and receiving circuit and which determines the resonant frequency at which the electrical power and signals are transmitted; and a second electrical receiving circuit comprising a receiving side of the coupler element and a load connected to the receiving side for receiving the electrical power and signals, wherein a signaling means is provided which generates a secondary coupling signal for the switching and amplifying element so that oscillation will take place at the resonant frequency; wherein the first electrical transmitting circuit and the second electrical receiving circuit move relative to each other.
