Introduction: Wireless Power Transfer (Simple and Fast Way)

Picture of Wireless Power Transfer (Simple and Fast Way)

I've been searching about this topic for a year to make a simple project. However i found nothing simple. Every project contains hard to find materials and high voltage. I'm trying to make it simpler. I also find a Hungarian site about this project. But i made some changes. Schematic in this site will also help you.

By the way if you don't have enough knowledge about electronics check this awesome course :

Step 1: Materials...

Picture of Materials...

Materials required;
(I give capacitors by using codes and values)

-  BD139 Transistor                                    /  1
-  5.1 K resistor (all resistors will work)   /  1
-  220n or 224 Capacitor                           /  1
-  4.7n or 472 Capacitor                            /  2
-  1.5pF or 102 Capacitor                          /  1
-  LED                                                            /  1
-  1N4148 Zener Diode                              /  1
-  Jumper wires
-  Cable for Coil 
-  9V Battery and Clip

Step 2: Making Coils

Picture of Making Coils

I made coils which have 7.5 and 4.4 cm diameter. Both work very well.How I don't know about numbers of winding. I use 1.5m cable.
Whatever... We need to make 2 coils, one for receiver and another for transmitter circuit. Receiver circuit need normal coil, no splice.
However the coil which is going to attached to the transmitter circuit is different. It needs a wire which is come out at the middle of the coil. This is the most important part otherwise the circuit may not work. 

Step 3: Making the Transmitter Circuit

Picture of Making the Transmitter Circuit

It's time to make transmitter circuit. I build this into breadboard but you can easily transfer into the perfboard. It's definitely much more steady.

Step 4: Making the Receiver Circuit

Picture of Making the Receiver Circuit

It is much more simpler than the transmitter circuit, so i directly soldered it onto the receiver coil which have 2 outputs.

Step 5: Result

Picture of Result

Now when you add 9V to the rails and put the receiver circuit to the top of the transmitter circuit it should light up. If it's not, check your connections and polarity of diode.

Step 6: Few Improvements and Version2 With 10000uF Capacitor

Picture of Few Improvements and Version2 With 10000uF Capacitor

I also made smaller coils and using white led with 10000µF Capacitor. It runs about 3 minutes.There are the results  :)

Step 7: Schematic

There is it ;

Note:I made it simpler this project not belongs to me. Just for entertainment and educational purposes only.

hey im trying to transfer 60w of power can you help me to understand how to determine the number of turns and the size of the coil needed to do so? thanks

aXce (author)2017-04-08

i use solar panel (2W and 9V) instead of 9V battery as its input but why my circuit is not working. can someone help me?

khalifababy (author)2017-03-20

can i use ceramic capaitors

komal5may (author)2017-03-14

@atakan atamert
can you please explain me the working of this project.

komal5may (author)2017-03-14

can anyone send the pdf to am unable to understand working of the circuit

nikosjurk made it! (author)2016-12-08

i made it but it does not work... can u figure out what's wrong?

jiendra kumar gola (author)2016-12-03

Kya hum power distumation ko wire less kar sakte hai

KailasD (author)2016-10-05

Sir can u please send circuit diagram of above project

HariC6 (author)2016-09-11

We tried this project but when we give tthe supply of 9v battery the bread board is starting melting

NaeemE (author)2016-07-25

I wanted to know how you came up with that value for the capacitor .i.e. 4.7 nF . I want to use 6.8 nF. What difference will it make?

rajswami (author)2016-07-14

is it possible to make it transfer for little more distance

TalariP (author)2016-07-03

Plzz wat abt d circuit diagram

HezrinHaze (author)2014-10-02

Done. :)

Sankalpshah (author)HezrinHaze2016-03-30

Hey Im struggling a lot with this project. Can You please send me details with circuit diagram at

Sonam33 (author)HezrinHaze2016-01-12

Can u please give me details..! I reslly need it

Well done you done better than me :)

plz send me the project circuit diagram and pdf plzzzzzzz

thanks man. i think i made this project the same time as you. got it from the same source you did. lol

can you send me the project details with pdf file plzzzzzzzzzzzzzz

SELVAKUMARM (author)HezrinHaze2014-10-10

This system is working upto how much distance?

HezrinHaze (author)SELVAKUMARM2014-10-12

the furthest mine went with 9v was 5cm with 50nF capacitor. :)

max 10-15 cm

AndresG32 (author)2015-11-08

Hi, I would like to increase the distance of transmition, because the one that the actual circuit gives me its too short, please help me

MohammadK57 (author)AndresG322016-03-16

Hello..can u help circuit as same with u but my circuit is still not working?

i m ee final year student.

SiddharthT (author)2015-03-26

i want to use this procedure to charge the mobile phone,then what changes i have to make.....

CollinCoil1 (author)2015-03-08

Nice Job! However contrary to your title, this relatively complicated. If you are looking for a really simple wireless power project, check out my instuctable on the matter at: . I think you'll find it easier.

surajgaikawad (author)2015-03-07

Sir why you used center tap winding and which oscillator you used in circuit.

surajgaikawad (author)2015-03-07

TanbirA (author)2015-03-06

I have completed this construction and the circuit diagram is working perfectly and the maximum distance is 15 cm but the problem is if I try with a repeater than it is not working. Can you explain why??

Also, It is obviously a DC chopper...please correct me if I am wrong.

jeuphatos jr. (author)2015-02-23

sir... what to do with the 3rd pin of the primary coil? if I solder it in the middle it seems the coil is shorted.. pls.

akhil.mithran (author)2015-01-18

also i need a circuit diagram for your circuit (not the original one) for my physics will also be very kind of you if you make theory and all of this, just the way you did with slayers circuit

akhil.mithran (author)2015-01-17

Can you pls upload a video of this project.......make it quick plssssss

frozen.tulip16 (author)2015-01-06

i made it but some one plz give me a report on it of about 35 pages plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz ASAP

odij (author)2014-12-01

I have done this project and the LED glows without diode :)
but i want to improving this circuit to charge 3.7 volt Li-Ion battery. Could you help me, what can i to do?
I want to me it like an adaptor wireless. Anyone can give me great idea ^,^

MichaelS20 (author)2014-11-22

what is the output voltage? Need to get 9v. Is this possible?

NAVEENS3 (author)2014-11-22


i have made it but its not working............................

help plzzzzzzzzzzzzzzzzzz

markk21 (author)2014-05-18

what is diameter of the both wires?

Atakan Atamert (author)markk212014-10-11

you can change it but they must be same

anayaka (author)2014-09-02

I have done it but its not working

Atakan Atamert (author)anayaka2014-10-11

be sure to double check your connections(exactly transistor) if you done everything correctly it should work well

tejaswiv (author)2014-09-24

which type of cable do we need to use for coil

Atakan Atamert (author)tejaswiv2014-10-11

just regular stranded cable

HezrinHaze (author)2014-10-02

The diodes on the recieving circuit is not necessary and the capacitor increases the recieving range. :)

kirangowda (author)2014-07-15

can i use any type of capacitors??

sr9 (author)2014-02-19

i have done the above project and the LED glows. how can i modify the above circuit so that i can glow a 60W bulb (or even a 15W CFL bulb) half meters away ?? how can i modify the above circuit??
