Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
A device that uses the principle of electromagnetic induction to charge, the principle is similar to that of a transformer, by connecting the transmitting end and the connecting endThe receiving end is set with a coil, the transmitting end coil sends an electromagnetic signal out under the action of power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
WPCWpc wireless charging technology The next step is to launch Ki kitchen appliance standard Wpc wireless charging technology , designed to provide kitchen equipment with unrestrained Wpc wireless charging technology wireless charging experience. Ki standards not only connect home appliances to power transmitters, but also introduce communication between devices to further enhance user experience and device intelligence.
Power Matters Alliance (PMA) standard Wpc Wireless Charging Technology : The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.
Qi is a Wireless charging standard created by the Wireless Power Consortium (WPC), its biggest feature is based on electromagnetic induction technology, strong compatibility, to achieve charging between different brands, different designs of equipment. In addition, the Qi standard also supports the simultaneous charging of multiple devices, automatic control of charging power and charging protection and other characteristics, improve Wpc wireless charging technology charging efficiency and safety, and bring convenient, efficient and reliable experience for people to charge.
Qi Qi is the world's first standardThe "Wireless charging" standard launched by the Wireless Power Consortium (WPC), a standardization organization that promotes wireless charging technology, has two characteristics: convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
2, WPC is the abbreviation of the Wireless Power Consortium (wireless Power Consortium), mainly an international organization of several companies to lead the wireless chargingThe development of technology. Its goal is to provide a wireless charging solution for devices such as smartphones, tablets, laptops, etc., to minimize the charging experience of rechargeable devices.
3, what is the meaning of wpc network, is the abbreviation of "Wireless Power charger" (Wireless Power Consortium). It is an organization formed by well-known manufacturers in the fields of electronics, information technology, communications, etc., to promote and develop international standards for global wireless power charging. So if you see a wpc logo when you buy a wireless chargerThen it should meet the relevant standards of WPC, you can rest assured to buy and use.
