Embodiment
According to embodiment, the present invention is further described:
embodiment 1
The present invention is a kind of Intelligent wireless charger receiver that can solve mobile phone wireless charging, comprise receiver casing, radio reception chip, peripheral resistance capacitance, receiving coil, receiver casing inside is provided with radio reception chip, peripheral resistance capacitance, receiving coil, transmitting terminal electric current returns when flowing through coil and produces magnetic field, when the coil that receiving terminal is not energized is near this magnetic field, will generation current, wireless charging is exactly the physical phenomenon by this electromagnetic induction, realize wireless charging, the cradle that wireless charging uses and the respectively built-in coil of terminal, make the two near just starting to power from cradle to terminal, receiving terminal completes the rectification of received current and the controlling functions of output voltage mainly through wireless radio receiving chip IDTP9025, powering load, radio reception chip be one highly integrated, meet the mobile wireless charging receiving chip of wireless charging alliance standard, it passes through closely magnetic field induction, can from the electric energy of wireless charging transmitting terminal transmission 5W, external inductors and two electric capacity are responded to from transmitting coil AC1 and the AC2 pin that the energy of coming is sent to radio reception chip and are gone to carry out full-wave rectification, then, internal bias circuit start, for raising the efficiency, remove the switch mosfet pipe controlling and drive in rectification circuit, the analog-to-digital control circuitry of its inside detects the voltage of RECT pin and the electric current of load, then the receiving chip that charges sends to wireless charging transmitting terminal according to the data detected, the data that transmitting terminal feeds back according to receiving terminal, increase and reduce the transmission of energy or stop the transmission of energy, detected by output voltage regulator and internal temperature and go to guarantee proper operation, energy conversion efficiency is made to reach maximum.The resonance frequency that transmitting coil produces is 110kHz-205kHz, the magnetic field that inductance L 1 is produced by the transmitting coil of energising, sense resonance ac supply signal, be transferred to 11 pins of IDTP9025, IDTP9025 is the radio source receiver chip of standard, there is control circuit its inside, rectification circuit, voltage regulator circuit, it can change the electric energy of 5W, resonance ac supply signal changes the stable linear output voltage of 5V1A into, to charging mobile phone battery by the rectification of IDTP9025 chip and the regulating rotary of output voltage.
