Balancing Output Power and Efficiency in Wireless Power Transfer




Anantha P. Chandrakasan


Inductive wireless charging is enabling new possibilities in ultra-low-power implantable medical devices. Due to charging time constraints, some wireless power systems are configured to output maximum power at the expense of efficiency. However, when the input power source becomes energy-constrained such as the case with energy harvesters, efficiency becomes critical for minimizing charging time. This project aims to create a wireless power system that minimizes charging time given an energy-constrained input by selecting the optimal amount of input buffering. Additional focus will be on the efficiency of other elements in the wireless power system such as the control circuitry.


I have worked with Prof. Chandrakasan and Marcus Yip at MIT developing a neural stimulator IC front-end. This past summer I interned at Apple to develop and validate critical hardware for touch sensors in the newest products. Previously, I taught science and technology to high school students at two different schools in China as part of a MISTI program.
