Magnetically coupled coils have been widely used
for a variety of applications requiring contactless or wireless power transfer (WPT). In this paper, the wireless power transfer (WPT) using Copper (Cu) and Aluminium (Al) as magnetic coupling is designed, fabricated and measured. A main problem of wireless power transfer (WPT) is about low efficiency. As state of the art, this research will investigate the effects of the use of copper and aluminum as magnetic coupling.
A Copper (Cu) and Aluminium (Al) are used as transmitter (Tx) and receiver (Rx) vice versa. A power analysis has been carried out to identify the efficiency system. The measurement result shown that the wireless power transfer (WPT) using aluminum
as transmitter (Tx) and receiver (Rx) have the highest efficiency. The overall efficiency of the power being transferred is about 7,51%-10,8% at distance 20 cm. This research shown that aluminum can consider as a material for the wireless power transfer with magnetic induction method.
