1, enamelled wire is good. Due to the skin effect of the high-frequency signal in the wire, which means that the high-frequency current in the wire will converge to the surface of the wire, the wireless charging coil generally uses a multi-strand enamelled wire to reduce the impedance.
2, the transmitting end is often multiple strands of silk-covered wire, multiple strands of thinner enameled wire or gauze wire wound inductors are used in relatively high frequency circuits, like the magnetic day of the radioWire rod coil, shortwave radio coil, high frequency transformer coil of liquid crystal display lighting circuit, etc., often use multiple strands of wire and wound.
3, enameled wire is an insulated wire coated with paint, so it can be wound into a variety of shapes of coils used in a variety of electronic devices, without producing the phenomenon of short circuit between wires. ● If it is not enameled wire, but a wire wrapped with other insulating substances, such as gauze wire, silk wire, insulating sleeve pipeline, etc., can also be used as a coil.
4, winding transformer usually used materials are enameled wire, sandbag wire, silk-covered wire, the most/p>
2, the resistance value of the inductor under test is zero, and there is a short-circuit fault inside. The size of the DC resistance value of the inductor under test is directly related to the enamelled wire diameter and the number of coils wound. As long as the resistance value can be measured, it can be considered that the inductor under test is normal. Note: If you need to determine accurate inductance and resistance values, please use special inductance testing instruments such as: impedance tester, LCR tester, digital bridge, etc.
1, the development of wireless charging technology stems from RFID near field couplingAt the heart of technological advances is the ability to install charging coils and rectifier chips on devices without software changes. There are several common installation methods: First, one uses induction coils and chips to form individual components in a wide range of sizes, from as small as a coin to a slightly larger 38x40mm. These components are made of metal copper wire tightly wound. 2, in summary, the latest progress of the WPC Wireless Charging Alliance shows that with the introduction of the Qi2 standard, wireless charging technology will be significantly improved in terms of security, stability, compatibility and so on. The implementation of Qi2 standard will provide users with more convenienceThe efficient charging experience promotes the wide application of wireless charging technology in many fields, laying the foundation for a more intelligent and green charging method.
3, this wireless charging technology must rely on two coils to convert electricity to achieve charging, that is, contact wireless charging; And its distance can not exceed 2 to 3 meters, after so many years of development charging distance has not made a breakthrough. Two days ago, SAN Jose-based startup Energous released WattUp wireless charging technology 0, and announced that vivo has become its WattUp wireless charging 0 technologyAs one of the companies. 4. The race to build a universal wireless charging technology is in full swing. New and exciting advances in wireless charging technology and products continue to emerge - some companies are focused on one technology, while others support multiple technologies. But the lack of interoperability between the various technologies is still a big problem, because there is no unified wireless charging standard. The idea of wireless power transmission has been around for years.
5, therefore, wireless charging does not belong to the category of artificial intelligence. Overall, wireless charging is a convenient power transmission technology, which greatly improvesThe user's charging experience. Artificial intelligence represents the latest advances in computer technology to simulate human intelligence. Although both are products of the forefront of science and technology, wireless charging does not contain the elements of artificial intelligence, and they shine unique light in the science and technology tree.
