In the last decade, the wireless power transfer (WPT) technology has been a popular topic in power electronics research and increasingly adopted by consumers. The AirFuel WPT standard utilizes resonant coils to transfer energy at 6.78 MHz, introducing many benefits such as longer charging distance, multi-device charging, and high tolerance of the coil misalignment. However, variations in coil coupling due to the change in receiving coil positions alter the equivalent load reactance, degrading efficiency.
In recent studies, active full-bridge rectifiers are employed on WPT receivers because of their superior efficiency, controllability, and ability to compensate for detuned WPT networks. In …

Wireless Power Transfer System With Power Factor Correction For Electric Vehicles, Michael Christopher Pickelsimer
Masters Theses
Wireless power transfer is currently a popular topic of research. Because there are no mechanical connections between the transmitter and receiver, power can be transferred whenever a system is within range of a transmitter. Coil-to-coil efficiencies of over 95% at multiple kW have been recorded by researchers, proving that this type of charger has the potential to be a viable charging solution. Electric vehicles are a primary target for this technology because wireless power transfer systems may be able to provide power both while the vehicle is stationary or while in motion.
Despite the promises of high efficiency and high …
