A novel capacitive power transfer (CPT) structure through self-capacitance routes is proposed in this paper. Selfcapacitance is the nature property of an isolated conductor which represents the amount of charges that have to be added to a conductor to promote its potential by one unit with respect to infinity. By utilizing the self-capacitance effects, one of the two coupling capacitors for conventional CPT can be eliminated. By attaching a metallic sheet to the Rx side, a virtual route can be formed through the injected self-capacitance to infinity. Based on the new idea, the equivalent circuit diagram is modelled and the system performance is analyzed. To verify the validity of the proposed structure, an experimental prototype is set up in the laboratory. A set of experiments are conducted with various transfer gaps. Both the theoretical and experimental results indicate the effectiveness of the proposed structure, with which a more convenient and more compact CPT system can be constructed.
