Abstract :
In this paper, we made a comparison between direct feeding and indirect feeding for the effect of shield to reduce the leaked magnetic field in the wireless power transfer with magnetically coupled resonance. As a result of the computer simulation, it is confirmed that the shields can suppress leaked magnetic field enough for both feeding structures. Particularly, it is observed that direct feeding can reduce a little more the leaked magnetic field than indirect feeding. On the other hand, it is found that indirect feeding is less susceptible by the shields than direct feeding in transmitting efficiency.
