Introduction: Wireless Mobile Charger

Wireless Charging is just what it sounds like — a way to charge your phone, tablet or other device without using any wires. Wireless charging is a simple as placing your device on a charging pad and letting the magic happen. The charger itself is of course connected to a power source, but your device doesn't have to be physically plugged in. Wireless charging has actually been around for years and seen in devices like the Palm Touchstone, however people are now most familiar with it in the form of Qi.

Step 1: Make Primary Coil or Transmitter

Picture of Make Primary Coil or Transmitter

Make primary coil of wireless charger. And it work as a transmitter, wound 30 turns of twisted copper wire in circle or rectangular shape.

You can use copper or Aluminium wire, But copper is a good conducting material its giver better efficiency.

Step 2: Make Secondary Coil or Receiver

Picture of Make Secondary Coil or Receiver

in receiver coil take 100 turn of 32 gauge no copper wire in circular or rectangular shape.


Step 3: Types of Coil

Picture of Types of Coil

Make this type of coils, Small coilThis for receiver and Big coil for transmitter

Step 4: Transmitter Circuit Diagram

Picture of Transmitter Circuit Diagram

Connect the all components as showing in figure 1,

This is the circuit diagram of transmitter section. And

provide 12 volt 1 Amp. DC power supply on Input side.


Step 5: Receiver Circuit Diagram

Picture of Receiver Circuit Diagram

Receiving circuit should be small in size, as you can see in video receiving circuit is placed in mobile back cover.

And use a full wave rectifier bridge circuit for convert AC to DC, because you will get AC output to the receiving and circuit and then it will convert in DC. Because mobile also charge in DC.

And a voltage regulator 7805 also gives you constant 5 volt DC.

5 volt is sufficient for a mobile charging.
