Abstract
Maximising power transfer efficiency (PTE) in resonant inductive power transfer (IPT) systems requires strong coupling between transmitter and receiver coils. In applications where system constraints yield a weak inductive link (e.g. significant distance between coils) or there is a requirement for a specific power level, then geometrically optimising the coils can enhance inductive linkage. To achieve this, a novel coil design method has been presented which provides maximum efficiency for both strongly- and loosely-coupled inductive links. A parameter (i.e. "Strong Coupling Factor") has been introduced to assist the design procedure. Discussing results from a practical 1.06 MHz inductive link - developed using the proposed design method - shows that, with proper selection of strong coupling factor (e.g. C=220), the designed coil geometry can provide maximum PTE of 86%. This is in close correlation (F ≈ 3%) with theoretical analysis using MATLAB.
