Özet

The share of capacitive wireless power transfer in recent wireless power transfer research has been increasing. The advantage of these systems mainly comes from their simple structures. The power is transferred between the plates, and there is no need for magnetic shielding as there is no magnetic field involved. The transferred energy depends on the capacitance of the plates, and increasing the effective area of the plate without changing its size can be effective. This paper proposes a simple technique to increase the effective area of plates. Basically, the effective area is increased by grooving the surface, like the fins of heat sinks. The proposed technique has been tested on a four-plate horizontal structure. The results show that the proposed method can be effective.
