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 is working, the input terminal will be AC mainsThe full bridge rectifier circuit is converted into direct current, or the 24V direct current terminal is used to supply power to the system. 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.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging is also known asInductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
The principle of wireless charging of mobile phones in a general sense is the process of converting electrical energy into a magnetic field, which is transmitted through the air, and then converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different. Wireless charging in the industry generally hasFour technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
