Design and Construction of Wireless Power Transfer System Charging Multiple Devices

Abstract:

Wireless  power  transfer  system  charging multiple devices, through inductive coupling method which is  classified  under  near  field  transfer  region.  In  this project,  we  intend  to  achieve  wireless  power  transfer charging  multiple  devices  such  as  mobile  phone, toothbrush and other low end power devices without the use  of  conventional  copper  wire  or  cable  between  the transmitter  module  and  receiver  module.  In  this  paper, result  analysis  was  taken  for  voltage  and  distance  of separation of coil of each receiving end device to know the efficiency  of  power  transfer  and  graph are  illustrated to show the comparison of voltage and distance of separation of coil of LED, DC fan, and mobile phone, digital camera, toothbrush.   Keywords :-  Wireless  power  transfer  charging  multiple devices, transmitter module, receiver module, mobile phone
