The power transfer can be done with the transmitter (primary) to the receiver (secondary) that is separated by a considerable distance (say 3cm). Therefore the power transfer could be seen as the TX transmits and the RX receives the power to run a load.
Moreover, the WPT technique can be used to charge gadgets like mobile phones, laptop batteries, iPods, propeller clock, etc. And also this sort of charging offers a far lower risk of electrical shock. Furthermore, this project can be enhanced by increasing the distance of power transfer as the research across the world is still going on
Thus, this is all about wireless power transmission, wireless power transfer circuit working and its applications which include simple electronic devices like mobile phones, mobile chargers, etc.. Wireless power transfer not only reduces the risk of shock and stops to plug frequently into the sockets. We hope that you have got some basic insights into this concept.
