In this project I will show you how to create an appropriate coil and an inverter circuit for a wireless energy transfer system that can easily transfer a power of 20W. Let's get started!

Step 1: Watch the Video!

The video should give you a basic understanding on how to create the coils and inverter circuit. The next steps will contain additional information to make recreating this project even simpler.

Step 2: Order Your Parts!

Here you can find a parts list with example sellers for the inverter circuit.

I got the transmitter and receiver coil from Conrad:


Step 3: Build the Circuit!

Here you can find the schematic for the circuit as well as pictures of my finished board. Feel free to use them as a reference.

You can also find the schematic on the EasyEDA website: https://easyeda.com/GreatScott/IR2113_H_Bridge-09e...

Step 4: Success!

You did it! You just created your own Wireless Energy Transfer System!

<p>hello,</p><p>i am beginner so maybe it can be dumm question.</p><p>i think there are more capacitors in result than in schematic. or do i miss something?</p><p>thank you for reply</p>
<p>What output voltage did you get on the receiver?</p>
that's a really neat project.... I had a question that I asked on your YouTube video. but you may have missed it... <br><br>I wanted to know if we can use this concept and replace coils with 1:1 transformer to create an isolated dc-dc converter.
Assuming you have none of these parts handy, whats the cost for this project. and if i did my math right thats a 4A current? trying to figure out if this will work to charge a large cell phone battery. xD
