Abstract :
In this paper, power transfer characteristics using resonance coupling between four-coils are experimentally shown and compared. Even though each circuit resonates in same frequency, optimum power efficiency is determined by its LC values of source and load due to coupling effects. Optimized four-coil system can achieve the efficiency of over 90% with fixed distance.
