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 AC power through the 2M active crystal inverterGive 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.
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of electricity to send electromagnetic signals.The receiving coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging.
Wireless charging principle has electromagnetic induction, magnetic field resonance and radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.

Such a circuit is difficult to implement and will drag down the chargeElectrical appliances, unless your charger limit is very small (which is not practical). Because the output voltage of the charger must be greater than the battery voltage when you charge (12V battery is generally not less than 18V), when you open the inverter, the battery voltage will be pulled to the original voltage of the battery (about 12V), so that your charger desperately needs to replenish energy to the circuit, and finally the charger is tired.
AH battery, load 10A, the load is too large, considering the battery life is only more than 50AH. In principle, the battery is charged with load, and the load current should not be greater than the charging current. You can refer to the backupType UPS circuit design.
On line means on the line of discharge. There is a connected electrical device or load. The load is battery powered.
