This report is about how to design and fabricated a wireless energy transfer system which is printed on flexible photo paper. That is a technology used to print conducting tracks on paper, or even entire circuit system. The circuit of wireless energy transmission is half bridge converter with spiral coil as the inductance which are etching in primary side and printing in secondary side.The procedure of fabrication will be introduced. While realizing the feasible simulation circuit, the optimal transmission energy system components are mounted according to the requirements. While looking for the best efficiency, it’s also neccessary to consider the appropriate size of the system. In the end of this report there will be some analysis which is aimed to identify where the largest electrical losses are located. Compared with ordinary PCB circuit board, printed circuit on paper makes the whole system very flexible and portable. When the primary side as close with secondary side, The efficiency is almost 72% while the 60Ω as the load. The output power is 10.68w. On the other hand, the ink of printed circuit on paper has high resistivity, which affects the efficiency of radio power system. However, for different paper substrates, the efficiency of wireless charging system will not be affected. |
