Wireless portable chargers, as a product of modern technology, have gradually penetrated every aspect of our daily lives, bringing immense convenience. They transmit energy to charging devices wirelessly, enabling charging without the need for cables. This article delves into the working principle of wireless portable chargers and specifically introduces Anker's wireless portable charger.

Principle of Wireless Portable Charger

 

Working Principle of Wireless Portable Chargers

The working principle of wireless portable chargers primarily relies on two physical phenomena: electromagnetic induction and electromagnetic radiation. In essence, they harness electromagnetic induction to transmit energy from a transmitter (charging pad or base) to a receiver (the coil within the charging device).

 

Electromagnetic Induction:

A wireless charger comprises two main components: a transmitter and a receiver. The transmitter generates an alternating current (AC) from a power source, which flows through a coil to produce an alternating magnetic field. The receiver coil, located within the charging device, senses this alternating magnetic field and converts it into electrical energy, which is then used to charge the battery. In the transmitter, AC is first transformed by a circuit board into medium-frequency AC, which is then used to create an alternating magnetic field through the coil. Meanwhile, the receiver coil, embedded in the charging device, induces an alternating current when exposed to the transmitter's alternating magnetic field. This alternating current is then converted into direct current (DC) by a rectifier circuit, which charges the device's battery.

 

Electromagnetic Radiation:

Alongside electromagnetic induction, electromagnetic radiation also plays a crucial role in the wireless charging process. The alternating magnetic field generated by the transmitter not only induces a magnetic field in the receiver but also radiates electromagnetic waves. These waves transmit energy, which is then converted into an alternating current in the receiver's coil. The alternating current is subsequently rectified into DC for charging the device. Through the synergy of these two principles, wireless chargers achieve energy transmission and charging capabilities wirelessly. This technology simplifies the charging process and enhances user convenience and flexibility.
