This paper reports on the design of multidimensional wireless power distribution using cellular concept, Helmholtz coils and cubical node design with power transmission capability over a distance of 6 m. To provide strong and uniform power delivery along the power transfer link axis, pairs of Helmholtz coils which are capable of creating uniform magnetic fields are used. To distribute wireless power in multiple dimensions the transmitter containing six secondary coils and one primary coil were used. The secondary coils orient magnetic files in six directions and the primary coil provides power transfer in the vertical direction. A cellular concept which permits the planning of power transfer over wide area is proposed. Furthermore, we have used a class E power source to power the transmitter. Class E power amplifiers provide stable resonant outputs to which the transmitter responds in sympathy. They also provide high voltage outputs and low currents making them safe for high voltage operations. The proposed cellular architecture with the multidimensional transmitter and receivers are demonstrated to be an excellent choice for inductive wireless power distribution over long distances. The multidimensional transmitter behaves like an inductive power coupler. With only one multidimensional transmitter and receivers, a range of about 6 m has been achieved end to end. The cellular architecture allows the power transfer network to be planned. Further range extension can be achieved by using a relay coil placed 9 cm above the primary coil.
