Abstract	Industrial devices are constrained by mobility due to power supply wires. In particular, safety accidents caused by mobile alternating current power are occurring in dark conditions inside the shipyard. Recently, research on wireless power supply for industrial devices requiring free mobility has drawn much attention. In this study, the wireless power transmission system was designed and verified by experiment results. As experiment results, the efficiency of the wireless power transmission was 85.5 [%] and the output ripple voltage of the wireless power transmission was less than 5 [%]. Moreover, the charged battery could be used for more than two hours.
