This paper describes the wireless power transmission for charging of mobile phone. In this paper, transmitter section and receiver section are described. In transmitter section, power supply, transmitting coil, controller and LCD (Liquid Crystal Display) to show simulation result. Receiving coil, regulator and output load are included in receiver section. The output voltage of power supply in transmitter section is fed to transmitter coil and also supplied the controller after through regulator. The controller (Ariduno Uno) controls the input voltage of transmitting coil by sending PWM (Pulse Width Modulation) to the MOSFET (IRFZ44N). The output voltage of the filter is connected to the one end of the transmitter coil to resonate the coil at particular frequency 500 KHz to 1000 KHz. Proteus Design Suite software has been used for simulation in the transmitter circuit.
