• Abstract:

  Wireless devices are not new; data

  become wireless long time ago. Because life of

  mobile phone device is always been a problem

  for the manufactures and people complain

  about it. Therefore scientists are rapidly trying

  to fulfill the demand of the people to charge safe

  and wirelessly. On demand of mobile users due

  to less charging time of android/cell phones,

  there is at most desire of wireless gadget for

  charging. In the design of a circuit a transmitter

  and a receiver circuit is used. The transmitter

  circuit has AC to DC rectifier circuit and then it

  is modulated to pulse width modulator circuit.

  Primary and secondary coils are connected

  by mutual induction and an emf is induced in

  a secondary coil. AC to DC bridge rectifier is

  used to transmit voltages to the mobile phone.

  Microcontroller with timer circuit is used to

  avoid over charging. It works on Faraday’s

  law of electromagnetic induction for significant

  reasons.
