How Wireless Phone Charging Works?
Wireless phone charging has become a convenient and popular way to keep our devices powered up without the hassle of tangled cords or lost charging cables. But have you ever wondered how it works? In this section, we’ll delve into the world of wireless charging and explore the technology behind it.
The Basics of Wireless Charging
Wireless charging, also known as inductive charging, uses electromagnetic fields to transfer energy between two devices: a transmitter and a receiver. The transmitter, typically a charging base or pad, contains a coil of wire that generates an alternating current (AC) magnetic field when an electrical current is applied. The receiver, usually the phone or device being charged, contains a coil of wire that is designed to resonate at the same frequency as the transmitter’s magnetic field.
When the two coils are brought together, the magnetic field induces an electromotive force (EMF) in the receiver’s coil, causing an alternating current to flow. This current is then converted to direct current (DC) using a rectifier and filter circuit, and finally stored in the device’s battery.
