Wireless Power Transmission with circuit diagram

This is my 12th standard project to transmit electricity wirelessly. Here is a wireless power transmitter and receiver circuit made by me. It has the ability to transmit power in short distance with high efficiency.

Key Points:

  • Transmitter is a high frequency oscillator which makes DC to  1.5MHz square wave.
  • Another coil which resonates at the same frequency picks up the power of the primary coil.
  • It does not need to use 8 capacitors in parallel. It requires a capacitor whose value approximately 54nF. Since the transmitter is a high current carrying one, use enough capacitor (3 or more) to get 54nF.
  • Transmitter loop is a 1cm sized copper pipe. Smaller the loop cause MOSFET to produce more heat. This is not good at all.
  • MOSFETs IRFZ44 and IRFZ48N will work. You can choose any, but both should be the same. I’ve tried with both type of MOSFETS.
  • If the power supply is not from a battery source, use any nF capacitor to filter AC.
  • Use capacitors polypropylene dielectric type(MKP/FKP type is recommended).
  • In the receiver side, use a solid copper with 5mm dia. with a 47nF capacitor in parallel.
  • I used a 12V, 21W bulb in the receiver side.

Really good! But if I increase the input voltage, can i charge a cellphone too?
Please let me know asap! Thanks!

    According to above description, the receiving side gets 12V, which is very higher than the requirement for a cellphone!

Greetings, Admin! Sir/Mam, I do really like your presentation even your circuit diagram, it’s the simplest diagram I’ve seen after all the research I’ve done.I follow the wiring and i find it very simple but the availability of materials is not easy. I’m asking you Sir to please record a video of the process of wiring, so that i can finish it correctly and i can find substitute for other components. Please, i do really need your help for my thesis. May God Bless you.
