What is Wireless Power Transmission? CRBTech.Electrical-Training
Most of the advancement in industries and applications that are relying on the contacting connectors, physical are more prone to failure and wireless power is the most reliable problem solver over here.

In the 1890s, Nikola Tesla experimented the Wireless Power Transfer although it came into action only in the last decade and today if you see; most of the devices uses the wireless technology like mobile, Internet, Bluetooth, cordless phone etc. It is also common in inductive coupling, resonant power transfer, Inductive Power transfer etc. Each of these devices follows the transmission of power from a power source without any connectors to the electric load in short wireless.

Working of Wireless power Through an oscillating magnetic field the transmission of load power from transmitter to receiver is the basis of Wireless technology. By specifically designed electronics into the transmitter you can achieve this by converting a DC supply to the power source into high frequency alternating current. For generating a magnetic field alternating current induces a copper wire coil in the transmitter. In the receiver coil the field can induce an alternating current within the proximity of the magnetic field where the coil is placed. CRBTech.Electrical-Training
The usable power or the DC current is produced by converting the alternating current by the electronics within the system. 1. The AC signal passing through the electronic transmitter circuit is converted into an AC signal by the mains voltage.

2. A magnetic field induced within a transmitter coil is extended into the receiver coil by the AC current. 3. The current flowing through the coil of the receiving device is generated by a magnetic field. Magnetic or Resonant coupling comes from the name where energy is transmitted between receiver coil and transmitter. The power for the device or the DC current is produced by converting the current flowing into the receiver coil. CRBTech.Electrical-Training
Define Resonance Resignation happens at the same frequency between the distance at which energy can be transferred between transmitter and receiver coils. An object vibrates naturally at a frequency similar to tuning fork at a particular frequency for achieving maximum amplitude is called resonant frequency.

Advantages of Wireless Power •Cost reduction with respect to maintaining direct connections (like those in the traditional slide ring). •Greater comfort for the usage of every day electronics. •Safe power transmission without any loss of data. •For reducing the risk of corrosion such as oxygen and water, electronics can be insulated. CRBTech.Electrical-Training
•High mobile industrial equipment and continuous power supply. •Irrespective of wet or dirty environment surrounding power supply is successful. Thus it can be said that wireless transfer plays a major role today when compared to physically wired connection which are slowly getting outdated. The future of wireless transmissions can also lead to developing smart home like today’s smartphone.
