Introduction to Wireless Charging
Wireless charging, also known as inductive charging, is a technology that allows for the transfer of electrical energy from a power source to a consuming device without the need for a physical connection. This is made possible through the principle of electromagnetic induction, where an alternating current (AC) in one coil induces a voltage in another coil. In the context of device charging, this means that a device can be charged by simply placing it on a charging pad or surface that contains the transmitting coil.
How Wireless Charging Works
The basic components of a wireless charging system include a transmitter (the charging base) and a receiver (the device to be charged). The transmitter contains a coil of wire, known as the transmitter coil, through which an alternating current flows, generating a magnetic field. The receiver, integrated into the device, contains another coil, the receiver coil, which is tuned to resonate at the same frequency as the transmitter coil. When the receiver coil is placed within the magnetic field generated by the transmitter coil, a voltage is induced in the receiver coil, which is then used to charge the device’s battery.
