1, magnetic charging is through the magnet male and female suction so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
2, 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 and introduction of many mobile phones and wireless chargersLine annotation.
3, the scientific and technological charm behind the magnetic charging treasure comes from its unique magnetic principle. Magnetic charging uses the gravitational force of the positive and negative electrodes of the magnet, as the magic of the magnetic force, to easily achieve wireless power transmission, so that the connection between the mobile phone and the charging bank is no longer a tedious insertion and removal operation, but a natural adsorption like the magnetic force.
4, wireless charging technology is derived from radio energy transmission technology, low-power wireless charging often uses electromagnetic induction, such as the Qi method of mobile phone charging, but ZTE's electric vehicle wireless charging method uses induction, high-power wireless charging often uses resonance. byThe power supply device transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
This component is a Printed Circuit Board Assembly (PCBA=Printed Circuit Board Assembly), which is composed of a combination of specific components welded to the printed circuit board of the function.
PCBA is Printed Circuit Board Assembly, Chinese translation for printed circuit board assembly. PCBA is the process of assembling and welding the electronic components (such as chips, capacitors, resistors, etc.) on the printed circuit board according to the circuit diagram, and physically and electrically connecting the electronic components and the printed circuit board to form a complete circuit system.
PCB refers to an empty circuit board. In this state, the board does not contain any electronic components and looks like green SLATE with dividing lines and Spaces. Therefore, unless and until the entire assembly is completed, PCB itself cannot be used for work. PCBA, on the other hand, is also known as the process of welding and assembling electronic components on circuit boards and finished/assembled circuit boards. The finished PCBA is actually used for electronic devices rather than PCBS.
PCB is a conductive path pattern based on a non-conductive medium used to support and connect electronic components. By mounting electronic components on the PCB and connecting them, the PCBA forms the structure and function of the circuit. The purpose of PCBA is to assemble different electronic components (such as resistors, capacitors, integrated circuits, etc.) together to achieve a specific function of the circuit board. Wireless charger transmitting and receiving circuit board, what is the use of each? The receiver is used to transfer the AC of the coil...
Wireless charging emission Circuit Board (PCBA) is an electronic component used to implement wireless charging function. It is one of the core components of the wireless charging system, responsible for converting electrical energy into wireless energy signals and transmission. PCBA usually consists of multiple components, including power supplies, inductors, circuit control chips, filters, and connectors.
Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coilAn electric current is generated to transfer energy from the transmitting end to the receiving end.
At the sending end and the receiving end, the wireless charger has a coil. There is an electromagnetic signal sent out in the sending single coil, and the receiving single coil can receive the electromagnetic signal sent out, and then the electromagnetic signal is converted into current, and the current enters the mobile phone, so as to achieve the effect of wireless charging. In simple terms, the wireless charger is actually a charging mode that relies on the energy of electromagnetic waves to convert electromagnetic waves into electricity.
Similarly, wireless charging technology also applies the principle of electromagnetic wave induction, and related AC induction technology, in the transmission and receptionA technology that uses a corresponding coil to send and receive inductive AC signals to charge, and users only need to put the charging device on a "flat" to charge, such charging methods have appeared in the past on watches and razors, but at the time could not be effectively charged for large-capacity lithium-ion batteries.
1, the working principle of the wireless charger: the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. Input when the system is workingThe AC mains is converted into direct current through the full bridge rectifier circuit, or the 24V DC terminal is used to supply power directly 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.
2, electromagnetic induction: the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end. It is the first generation of mobile phone wireless charging, and the technology is mature, but it can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), rather than single-to-multiple charging like WiFi.
3, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil to receive electromagnetic signals and electromagnetic signals into current, so as to achieve the purpose of wireless charging.
