Summary:Efficiency improvement of wireless power transfer system is studied using ferrite bars with keeping distance of electric power transmission. Experiments are performed to decide better installation of ferrite bars for improving efficiency; there are many possibilities how and where to install them. We conducted several experiments and devised a method of installing ferrite bar with high effect on WPT. Each result is compared with the case of no ferrite bar system. The result of experiments shows using ferrite bars is practical and cost effective. Some suggestion is given to drive wireless power transfer system with lower frequency, which is also noteworthy about the limitation of available power source.
