Abstract

This paper proposes a contactless charging platform that allows portable devices being placed and charged. Using wound-wire structure and electro-magnetic induction, contactless power transmission can be achieved between platform and electronic devices. The charging platform adopts a microcontroller to select the appropriate array coils to be activated. The proposed array structure not only retains the original sensing area but also detects the secondary-side coil position to drive the primary-side coil and charge the load. The experimental results show that the secondary-side output voltage is 4.96V when the induction coil displacement is smaller than 2mm. The maximum output power and the maximum transmission efficiency are 3.43W and 64%, respectively.
