how to get Wireless charging methods of different cell phones - 5 System Specification

This research project is primarily empirical. There are many variables in the system that can change the voltage that is developed. The stage capacitors need to be optimized. The number of stages needs to be determined that, combined with the capacitor values for each stage, will result in a sufficiently high voltage level to turn on the phone and charge the phone’s battery. Also, a capacitor can be used across the output as a filter to provide a flat DC signal and store charge. The value of that capacitance also needs to be determined. There really are no fixed parameters for any of these values. The only specified value for any element in this research is the frequency that is being transmitted to the station. This frequency is to be 915MHz.

In this thesis, we submit a first step towards a goal that would have profound ramifications on the cellular phone industry and the portable electronic device industry as a whole. Experimental results show that while we were not completely successful at achieving our overall goal of having the charging circuit in a stand be able to charge the battery of a cellular phone while it was within the phone using a wireless RF source, we have completed the goal of being able to charge the battery while the phone is in its stand. Circumventing the proprietary circuitry in the charging path will allow future adaptation of the wireless RF energy harvesting concept produced by this research.
