Wireless Power Transmission

Wireless power transmission is an updated technique of power transmission without using any wires in the medium. A wireless transmission transfers power from the generation station to the consumer without using towers and transmission lines. Wireless Power Transfer (WPT) is the process where electrical energy is transmitted from a power source to an electrical load across an air gap using induction coils. These coils produce an electromagnetic field that sends energy from a charging base station (transmitter) to a coil on a portable device (receiver) with complete galvanic isolation. The receiver coil takes power from the electromagnetic field and converts it into electrical power.

Working of Wireless Power Transfer:

• Wireless power transfer works on the principle of electromagnetic induction.
• A transmitter placed on the generation side generates flux to link with the receiver end.
• At the consumer end, we will place a receiver it receives the flux and covers it with electricity.
• It will be used for a permissible distance, by using solar power satellites we can transfer power anywhere in the world.
• In the solar power satellite transmission, We just need to place a transmitter at the satellite end. We can place receivers wherever need power on the earth.

Wireless Power Transmission through Solar Power Satellites:

Solar power transmission using solar satellites was first introduced in the 1970s. The solar satellites generate power using their solar panels by using the sunrise 24/7. And the power generated will be transmitted by a transmitter in the form of microwaves. On the earth,  for every consumer, we will place a receiver on the roof of the building. Here the receiver receives the microwave and it converts the received waves into electricity. 

Applications of Wireless Power Transmission:

• Wireless power transmission is used in place of transmission lines to transfer power from one place to another place.
• It is also used in distribution systems to transfer power to the consumers.
• It is also mostly used in industries and all electrical applications.

Advantages:

• By using solar power satellites,  we can produce unlimited energy resources.
• We can deliver energy anywhere in the world. 
• The cost of distribution and transmission becomes less.
• The power could be transmitted to various places which do not contain the wired transmission.
