Wireless Power Transmission Circuit With Its Working

In this modern age, electricity is one of the basic requirements for humans all over the world. Production of making electricity is risky for the environment. Energy information records clear that 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 very dangerous for human beings 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  Wireless Power Transmission(WPT) Technology.

Wireless Power Transmission Circuit

Wireless Power Transmission Description

WPT technology was purposed by “Nikola Tesla” in the year 1980. Wireless power transmission mainly uses three main systems like microwaves, solar cells, and resonance. Microwaves are used in electrical devices 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 a receiver device without using any wires. This system consists of two coils they are a transmitter coil & a receiver coil. The transmitter coil is powered by AC current for the creation of a magnetic field and the receiver coil is used to observe the magnetic field.

Wireless Power Transmission circuit

The blog diagram of power transmission wirelessly is given below. This blog diagram is very useful to understand the main root of WPT.

Wireless Power Transmission

A simple wireless power transmission circuit is shown above. It is a very simple WPT circuit with only one transistor. The whole system consists of two parts as Transmitter and receiver.

Components Required for WPT

  • Transistor
  • Copper Wire
  • Battery
  • LED

Circuit Diagram of Wireless Power transmitter

The transmitter of the wireless power transmitter is given below its simple and low power circuit diagram. The power of this circuit can be increase by using powerful components.

Circuit Diagram of Wireless Power receiver

The circuit diagram of WPT is given below in an animated shape.

Circuit Diagram of Wireless Power receiver

Power transfer can be done by the primary to the secondary. Here transmitter is primary and the receiver is scan dry. 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 phones, laptop batteries, iPods, propeller clock, etc wireless. And there is no risk of electrical shock as it would be galvanically isolated.

Applications of Wireless Power Transmission
