摘要：
Currently, a “sandwiched structure” is being used for the wireless power transmission system, which is suitable for personal mobility. The sandwiched structure is constructed with two power receiving coils sandwiched between two power transmission coils. This structure stabilizes power transmission, regardless of changes in position of the power receiving and power transmission coils. However, detailed circuit analysis of this structure has not been performed, and analysis considering the mutual inductance of multiple coils is required. In this study, by clarifying the six mutual inductances of the four coils used in the sandwiching structure and performing circuit analysis, the effects on the efficiency were verified. We also performed experiments to prove that the theoretical analysis was correct. © 2022 The Institute of Electrical Engineers of Japan.
