Wireless charging, as an emerging charger, has evolved into a popular view in recent years and its accessibility and efficiency have been well received. However, the rationale for wireless charging is widely discussed, with one saying that wireless charging is based on tesla coil. Is this view correct, then
To answer that question, we need first to know what the tesla loop is and how it works. Tesla loop, invented in 1891 by american serb scientist nikola tesla, is a transformer that uses resonance principles to generate ultra-high voltage but low current, high frequency communication power. Tesla circles consist of two (or three) paired resonance circuits, which can achieve wireless transmission of energy by changing their internal parameters. This technology has a wide range of applications in modern wireless communications, and mobile communication devices such as mobile phones are designed on the basis of this principle。
Now, let's see how wireless charge works. The current dominant wireless charge technology on the market is based mainly on four modes of electromagnetic induction, magnetic field resonance, electric field coupling and radio-wave reception. Of these, the most similar to tesla coil principles are the magnetic field resonance radio charge. This method is resonance through two magnetic fields at the launch and receiving ends, thus enabling the transmission of electrical energy. When the resonance frequency of the two magnetic fields is the same, the energy conversion between them is the most efficient, thus achieving a rapid charge。
As we can see from the above, although the magnetic field resonance approach in wireless charge is somewhat similar to that of the tesla coil, it is not identical. Tesla coils are mainly transmitted wirelessly by changing internal parameters, while magnetic field resonance wireless charge is converted by adjusting the resonance frequency of the launch and receiving end. In addition, tesla wires are used mainly in laboratory and scientific fields, while wireless charge technologies are widely used in consumer electronics。
We can conclude that wireless charge is not based solely on tesla coil principles, but it does draw on some of the tesla coil concepts and techniques. As science and technology continue to develop and innovate, wireless charging technologies will become more mature in the future, making life easier for people。
