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 24V DCThe electrical end directly supplies 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 technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.

Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The charger end will generate alternating current in the magnetA vortex is formed in the field, and the receiving coil on the mobile device senses this vortex.

Specifically, wireless charging devices mainly include two parts: transmitter and receiver. The transmitter generates a high-frequency alternating magnetic field through a built-in coil, and the coil inside the receiver receives the magnetic field energy and converts it into electricity, thus charging the phone.
