In this modern age, electricity is one one of the basic requirements to human in all over the world. Production of making electricity is risky for the environment. Energy information records clear that the 50% of all electricity plants are running with coal and due to that Various changes in the environment have happened over the last thirty years. Which are vary dangerous for the human being as well as animals and plants. To overcome this problem, We are trying to diminish greenhouse gas emissions into the soil’s atmosphere. The alternative power generation is WPT (Wireless Power Transmission) Technology.
WPT (Wireless Power Transmission) Technology
WPT technology was purposed by “Nikola Telsa” in the year 1980. Wireless power transmission mainly uses three main systems like microwaves, solar cells and resonance. Microwaves are used in electrical device for the transmit-ion of electromagnetic radiation from a transmitter to a receiver. Wireless power transmission states that, the electrical power can be transferred from a source to receiver device without using any wires. This system consists of two coils they are a transmitter coil & a receiver coil. Transmitter coil is powered by AC current for the creation of magnetic field and receiver receiver coil is used to observe magnetic field.
Wireless Power Transition circuit
Simple wireless power transmission circuit is shown above. It is very simple WPT circuit with only one transistor. The whole system consists of two parts such as Transmitter and receiver.
- Copper Wire

Power transfer can be done by the primary to the secondary. Here transmitter is primary and receiver is scandry. So the transfer could be seen as the primary transmits and the secondary receives the power to run a particular load.
This method can be used in several applications such as charge gadgets like mobile phone, laptop battery, iPod, propeller clock etc wireless. And there is no risk of electrical shock as it would be galvanic ally isolated.
Applications of Wireless Power Tranmission
Some applications of WPT are as follows
- Uses in Consumer electronics
- Transport use
- Heating and ventilation
- Industrial engineering
- Model engineering
