This circuit acts as both, step up Voltage converter and also wireless electricity transmitter and receiver. This is a really easy project to do, and could be used in many ways if improved.Follow instructions in this video and you can build your own wireless power transmission.
Wireless power transfer wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy from a power source to an electrical load.
How Does it Work?
The Direct Current is converted into high frequency Alternating Current (AC) with the help of transmitter circuit.This alternating current energizes the transmitter coil which generates magnetic field.When secondary coil (receiver) is placed near to the primary coil, the changing magnetic field induces an alternating current in it.
