Wireless Power Transmission with circuit diagram

This 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.
