Hannan and S. A. Samad and A. Hussain}, country = {}, institution = {}, abstract = {This paper deals with the modified wireless power transmission system for biomedical implanted devices. The system consists of efficient class-E power amplifier and inductive power links based on spiral circular transmitter and receiver coils. The model of the class-E power amplifier operated with 13.56 MHz is designed, discussed and analyzed in which it is achieved 87.2% of efficiency. The inductive coupling method is used to achieve link efficiency up to 73% depending on the electronic remote system resistance. The improved system powered with 3.3 DC supply and the voltage across the transmitter side is 40 V whereas, cross the receiver side is 12 V which is rectified to meet the implanted micro-system circuit requirements. The system designed and simulated by NI MULTISIM 11.02. }, journal = {International Journal of Biomedical and Biological Engineering}, volume = {7}, number = {12}, year = {2013}, pages = {799 - 802}, ee = {https://publications.waset.org/pdf/9996625}, url = {https://publications.waset.org/vol/84}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 84, 2013}, }
