Golden Eagle Coil will introduce to you the principle of wireless charging coils.

Wireless charging, also known as inductive charging technology or wireless energy transmission technology, is a non-contact type of alternating current induction charging technology that does not require wires and does not require additional wire connection points on the devices.

Wireless charging devices usually conduct energy through coils, or they can receive power from an external power source. Once the set current is reached, the device will automatically shut off.

The wireless charging coil mainly consists of a coil, a driving circuit, an electromagnetic field coupling mechanism and a driving coil. The energy transmitted by the wireless charging coil is mainly the magnetic energy generated by induction, which is the product of the magnetic induction intensity and the alternating current.

The main aspects of the wireless charging system are as follows:

(1) Electromagnetic Compatibility (EMC): In an electromagnetic environment, if there is an electromagnetic field present, electromagnetic interference will occur. Under such circumstances, the requirements must be met to ensure that the product does not interfere with the normal operation of other devices.

(2) Radiation protection: The electromagnetic radiation in the wireless charging system is not necessarily harmful to the human body. To ensure human health and personal safety, it is necessary to prevent the radiation from the product from causing harm to the human body.

(3) Short-circuit protection: In the event of a short circuit, it can immediately cut off the power supply.

(4) Overcurrent Protection: When the current in the wireless charging system is too high, it may cause faults in the insulation layer of electrical components or in the circuit, resulting in the activation of electrical components or circuit breakage. To prevent faults caused by the activation of electrical components or circuit breakage, an overcurrent protection device should be installed in the circuit.

(5) Discharge Protection: In a wireless charging system, if the discharge occurs too rapidly, it can cause damage to the components; if the discharge current cannot maintain a certain duration, it will lead to insulation breakdown and result in short circuits and other phenomena. To prevent such potential safety hazards, effective safety measures need to be taken to reduce the probability of danger occurrence and minimize the degree of harm.

In the wireless charging system, there must be a safe, reliable and reusable power circuit; electromagnetic interference is an important aspect that needs to be considered in the wireless charging system; safety regulations are a broad and wide-ranging concept. Different industries have different requirements for safety regulations.
