Wireless Charging Coils

Wireless charging coils are rapidly becoming a mainstream technology due their primary benefit of no need for cables or electrical connections. Instead, energy is transmitted and received between two paired electromagnetic coils at close proximity.

The charging device, such as the 760308100110, consists of two separate components; a transmitter and a receiver. The transmitter is connected to a conventional power source and it generates an oscillating electromagnetic field. The receiver is designed to receive power from the field via its own coil.

Application Field

Wireless charging coils, such as the 760308100110, find application in many fields including medical, automotive and consumer electronics. Medical applications include remote monitoring and controlling implants, such as pacemakers, for battery recharging. In automotive, wireless coils are used for wireless charging of batteries in electric vehicles. In consumer electronics, it is used to wirelessly recharge mobile phones, digital cameras, laptops and tablets.

Working Principle

The working of the 760308100110 is based on Faraday’s law of electromagnetic induction. When an alternating current flowing through a conductor produces a changing magnetic field it causes an induced voltage to be generated in an adjacent conductor.

When two separate coils are placed in close proximity, it establishes a transformer circuit. In the transmitter coil, the external source of alternating current sets up an oscillating magnetic field. The magnetic field created by each cycle of the alternating current induces an electric potential in the receiver coil.

The voltage that is generated in the receiver coil is then rectified and used to charge the battery. The frequency of the current determines the rate of electricity transfer through the receiver coil.

Advantages

The primary advantage of the 760308100110 is that it eliminates the need for physical wiring and hence reduces the complexity and cost of electrical installation. Furthermore, it enables a wireless connection between the electrical source and the device being charged, enabling automatic charging without user intervention.

Wireless charging coils are also more secure since the power is received only if the transmitter and receiver coils are at close proximity. Also, due to the high frequencies used, the potential for radio interference is low.

Conclusion

Wireless charging coils, such as the 760308100110, are becoming more widely adopted due to their benefits of convenience, security, and cost savings. They are an ideal solution for many applications in medical, automotive and consumer electronics. The main working principle, based on Faraday’s law, is promising in terms of its ability to provide long-term, efficient power delivery.
