| Abstract(in English) | In magnetic coupling wireless power transfer, the kQ theoretical formula that indicates maximum transmission efficiency ηmax is very useful. This is a theoretical formula when there is one pair of transmitting and receiving coils. On the other hand, no specific theoretical formula for multiple magnetic coupling has been found. Author investigated the construction of an extended kQ theoretical formula for multiple magnetic coupling based on this kQ theoretical formula. As a result, although the conditions are limited, an extended kQ theoretical formula that matched the theoretical values was obtained. Using this formula, evaluated the efficiency characteristics when the number of receiving coils and the number of transmitting coils, and obtained useful knowledge. |
