摘要: State of the Art Wireless Power Transfer (WPT) systems, based on conventional copper coils, are known to exhibit efficiencies well above 90% when operated in resonantly coupled mid-range regime. Besides full system efficiency, area- and weight-related power densities transmission coils key figures merit for high applications. We report a fully functional WPT system, consisting single pancake HTS transmitter receiver side, which exceeds density most systems. Despite compact coil size, DC-to-DC efficiency 97% is achieved at 6 kW output power. Next fundamental design, we show analytical numerical simulations AC loss taking into account both hysteresis eddy current contributions. The results validated by experimental measurements obtained standard lock-in technique up frequencies 4 kHz. Finally, present performance different load conditions.
