A High-Efficiency Low Power Rectifier For Wireless Power Transfer, Zachary Loy, Alden Fisher, Brian Vaughn, Dimitrios Peroulis

The Summer Undergraduate Research Fellowship (SURF) Symposium

With the number of implantable devices that utilize electronics increasing, there is an increasing need to find alternative ways of powering them. Currently, surgery is required to replace a battery for these devices; however, with advancements in Wireless Power Transfer (WPT) methods, the need for further surgeries will become negated. This paper explores the ability of WPT as an alternative powering method by investigating rectifier Power Conversion Efficiency (PCE). The rectifier converts high frequency waves to Direct Current (DC) energy that can provide usable power to devices requiring electrical power. It is targeted for low power applications centered around a …
