ABSTRACT
This paper introduced the use of a power transmission technology, wireless power
supply technology model, using the principle of electromagnetic induction and the
induction technology,intelligent wireless charger for charging the AC signal based on the
STC12C5A60S2 single-chip microputer to control the transmitting end and the
environment and other requirements continue to increase, the power transmission mode
of contact to meet the actual needs bee more and more difficult. At the same time,
wireless power transmission system, get rid of the limit line, pletely separate electrical and
power, with the wireless transmission of electrical energy, the equipment has the
advantages of small volume, high transmission efficiency, easy to carry and integration.
In the rapid development of science and technology in 21 Century, the prospects for the
development of intelligent wireless charger .The design through the design of the
hardware part and the software part of the system to achieve the wireless energy
transmission, within the specified range of the transmitting coil in small appliances such
as mobile phone, MP3 and other direct charge. The hardware part includes efficient DC
power module, drive module, display module, control module and so on; the software
part is mainly based on the design thought of the system design of the main program and
the subprogram flow chart, and through the C language to achieve the corresponding
programming requirements. relationship between the circuit parameters and the output
power of the system. The design and fabrication of resonant coupling wireless device,
using the LCD1602 design draw progress bar shows charging, charging voltage, charging
time display.
