Resonant wireless power transfer with embedded communication for more versatile and efficient applications

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2016.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 237-240).This thesis explores the feasibility of embedding communication within the power transfer channel of a near field wireless power transfer system in order to increase the versatility and efficiency of the system. The system was built around the LTC4125 auto-resonant wireless power transmitter IC. Both the transmitter and receiver were tuned to approximately 100kHz with a communication data bit rate of 1kHz. The thesis covers both resonant wireless power transfer theory, the details of the embedded communication and the results obtained.by Erik Johnson.M. Eng
