The transmitter and receiver for wireless power transfer (WPT) need information interaction to achieve optimal efficiency if the mutual inductance load are movable. This paper proposes a parameter estimation system based on digital-twin concept aiming condition monitoring of WPT. digital replica physical experimental demonstrate an application series-series WPT system. A hybrid optimization alg...

Abstract In this paper, a Buck converter is designed to make the transmission of WPT stable and not susceptible load changes. This ensures stability end by changing duty cycle, so that always works efficiently. The hardware structure design program are discussed in correctness verified simulation PSIM.

Radiating wireless power transfer (WPT) brings forth the possibility to cost-efficiently charge devices without requiring a wiring infrastructure. As such, it is expected play key role in deployment of limited-battery communicating devices, as part 6G-enabled Internet Everything (IoE) vision. To date, radiating WPT technologies are mainly studied and designed assuming that located far-field reg...

Magnetically coupled resonant wireless power transmission technology (WPT) based on high-temperature superconducting (HTS) coils has gained wide popularity due to its low impedance and high-quality factor Q value characteristics. This greatly improved the energy transfer performance of systems. However, practical applications conventional WPT, such as charging autonomous underwater vehicles at ...
