Abstract

This paper investigates the application of resonant wireless power transfer (WPT) technology to surface acoustic wave (SAW) devices. By analyzing the WPT system with SAW devices as loads, this study examines the operating principle of the system and highlights the effect of impedance variation at resonant frequency on power transfer and efficiency. The study also proposes a design to compensate the reactive power generated by the SAW device at resonance. Simulation results show that the proposed asymmetric WPT system designed for SAW devices is 7.4% more efficient than the conventional symmetric compensation topology, and the peak power efficiency of 95.2% using the WPT system to power SAW devices.
