USER MANUAL
Product:Wireless Charging
Model No:KT-10W-24V
This is a wireless charger that will charge any device that supports the Qi standard. Please read the user manual before using and keep it for future reference.
Working principle
Wireless charging transmitter is a wireless charging solution based on
electromagnetic induction technology provided by CPS. It is compatible with
QI-BPP/Samsung Fast charging standard, with charging area up to 10mm*10mm and
output power of 10W supporting It is based on the QI (WPC 1.2.4) standard
using near-field electromagnetic coupling and the power carrier amplitude
modulation method to implement power transmission between the transmitting and
receiving units.
The receiving unit receives the power electromagnetic energy transmitted by
the transmitting unit and converts it into a DC current output to the power
consumption part, and the receiving unit determines whether the received power
requirement is met by detecting and calculating the received voltage and
current, and converting the requirements into signal modulation on the power
carrier, the transmitting unit returns the signal of the carrier amplitude
change to the communication digital signal to the main control chip of the
receiving unit, and the main control chip adjusts the output power according
to the received information until meet power requirements at the receiving
end.
After the wireless charger transmits part, in a short period of time, the main
control chip completes the communication between the self-test and the power
adapter, determines the power range that can be output, and then starts
sending the detection signal to the load: such as the detection signal and the
PIN information. The control chip sends a PIN control signal to the full
bridge power part ,converting it into the electromagnetic power carrier , and
if there is no load, it is sent intermittently.
When there is load, the load receives the power electromagnetic energy and
responds to the information according to the requirements of the QI standard.
The information is modulated on the power carrier by the receiving coil. The
modulation of the receiving end causes a slight amplitude change of the
voltage amplitude of the power carrier.
