2. Circuit principle description
1、The principle of wireless charging: a device that uses the principle of electromagnetic
induction to charge, similar to a transformer, has a coil at the transmitting and receiving ends,
the transmitting end coil is connected with a wired power source to generate an
electromagnetic signal, and the receiving end coil senses an electromagnetic signal at the
transmitting end, thereby generating a current to Power equipment such as batteries. That is,
wireless charging technology requires two devices: RX (receiving device, which is the product
to be charged), TX (transmitting device)
2、USB principle: The voltage that is not suitable for direct charging of the mobile phone is
directly adjusted to the voltage directly used by the mobile phone through the DC TO DC Buck
