.pptx   WIRELESS MOBILE CHARGING.pptx (Size: 156.78 KB / Downloads: 29)


The wireless charge will convert the
RF signal at 900MHz frequencies into a
DC signal ,and then store the power into a mobile battery.


The wireless battery charger is designed to operate at 900Mhz.
power transmitter acts as the power source.
Power transferred to the receiver is connected to DC signal.
Charging circuit will store power into the mobile battery.


an antenna was connected through an amplifier to a radio-frequency (RF) source.
The RF source is a circuit that outputs a signal at a user-specified frequency and voltage. The range of frequencies of the signal generator resides in the radio frequency band, 3 mega-hertz (MHz) to 3 giga -hertz (GHz).
The transmitting antenna is called a patch antenna and is fabricated from copper plating that soldered to a feed wire and has a ground plane.


The considerations of
choosing the appropriate antenna are
Impedance of the antenna
Gain of the antenna
The impedance of the antenna should match with the output impedance of the power transmitter and input impedance of the rectifier circuit


The receiver’s main purpose is to charge a battery. A simple battery charging theory is to run current through the battery, and apply a voltage difference between the terminals of the battery to reverse the chemical process.


RF energy using an antenna, input it into a charge-pump and use this energy to power some other circuit
These project and implimentations range from tuning the charge pump to using results from existing charge pumps to drive other circuits
testing is done using a light emitting diode (LED)
RF energy is transmitted to the circuit and the charge pump stores the energy in a large capacitor.
When the amount of charge is large enough, the LED uses the stored energy to light for a moment. This is called a charge-and-fire system
This type of technology is very useful in Radio Frequency Identification (RFID) applications


In older systems, the frequency or amplitude of this signal was modulated by the chip and sent back. This technique is called backscatter
the chips are getting more complicated and require much more power to run
The RFID system is unsuitable for batteries mostly because they have to be small
with a good antenna, a charge pump should be able to handle the powering of these circuits and never will need to be serviced. Because the circuits are small, the power required is minimal.


In this paper we submit a first steps towards a goal that would have profound ramifications on the cellular phone industry and the portable electronic device industry as a whole. Even though our project and implimentation proceedings show that we are not completely successful at achieving our overall goal of having the charging circuit in a stand and be able to charge the battery of a cellular phone while it was within the phone using a wireless RF source, we are still putting our heart and soul to make this dream turn a reality.
