ABSTRACT
This chapter provides an ensemble of innovative techniques in wireless power transfer. A concentrator increases the flux coupling coefficient and hence leads to increased flux delivered to a receiver by a large order of magnitude, while the separator reduces crosstalk between two identical types of nodes and also leads to significant increase in power delivery. The easy-to-use algorithm for the transfer function equations assumes also low power coupling approximation which applies to many current applications of inductive methods. The assumptions lead to the power transfer equation for any N coils. The fifth coil is called the flux concentrator. It is a well-established fact that the amount of magnetic field coupled to another coil is larger if the distance between the coils is smaller, and it is therefore reasonable to conceive continuously, strengthening the flux by using concentrators located at shorter distances to bridge the distance between the primary and secondary coils without losing range.
