Publication number: 20240112853Abstract: The present application relates to an apparatus which comprises a wireless power transfer system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference, and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage.Type: ApplicationFiled: September 11, 2023Publication date: April 4, 2024Inventors: Pavel Shostak, Oleg Los, Unnati Wadkar, Jason Luzinski, Md. Nazmul Alam, Mark D. Melone, Matt Zamborsky, Jacob Babcock, Alberto Peralta, Christine Frysz

Publication number: 20240079909Abstract: A system for wireless power transfer includes a wireless transmission system, a wireless receiver system, and a dynamic tuning controller. The wireless transmission system configures an electrical energy signal, using the power from the input power source, for transmission by a transmission antenna. The wireless receiver system is operatively associated with a load and is configured to receive the electrical energy signal from the wireless transmission system, via coupling of the transmission antenna and receiver antenna, and configure the electrical energy signal to transfer power to the load. The dynamic tuning controller is configured to determine an output of the system and determine existence of disturbances to the system, based on the output, control alterations to one or more forward gain elements of one or more of the wireless transmission system, the wireless receiver system, and combinations thereof, if one or more disturbances exist, based on the output.Type: ApplicationFiled: September 11, 2023Publication date: March 7, 2024Inventors: Alberto Peralta, Pavel Shostak, Jim Crnkovic
