摘要: It is sometimes unavoidable to use loosely-coupled coils in applications, such as biomedical devices, for transferring electric energy wirelessly. However, coil misalignment would cause unwanted degradation of the power transfer efficiency. A structure that consists two orthogonally-placed windings transmitter investigated this paper. Such lessens variation coupling between transmitting and receiving sets under situations. driving mechanism maximizing efficiency will be discussed. An experimental prototype has been built evaluated lateral angular misalignments. Experimental results confirm merits are close agreement with theoretical predictions.
