Journal ArticleDOI
A Rotation-Free Wireless Power Transfer System With Stable Output Power and Efficiency for Autonomous Underwater Vehicles
TL;DR: In this paper, the authors proposed a rotation-free wireless power transfer system based on a new coil structure to achieve stable output power and efficiency against rotational misalignments for charging autonomous underwater vehicles.
Journal ArticleDOI
Frequency Optimization of a Loosely Coupled Underwater Wireless Power Transfer System Considering Eddy Current Loss
TL;DR: An underwater WPT prototype was built and the experimental results verified the theoretical analysis, finding that the optimum operating frequency is supposed to be larger than the resonant frequency to achieve the maximum dc–dc efficiency in the seawater.
Journal ArticleDOI
Eddy Current Loss and Detuning Effect of Seawater on Wireless Power Transfer
TL;DR: In this article, a modified mutual inductance circuit model of an underwater WPT system was proposed to analyze the eddy current loss (ECL) and the detuning effect caused by the seawater.
Journal ArticleDOI
Fault-Tolerant Wireless Power Transfer System With a Dual-Coupled LCC-S Topology
TL;DR: The proposed WPT system can provide a stable output and can tolerate both short- and open-circuit faults at the output, and can be used for the wireless charging of e-mobility scooters and autonomous underwater vehicles.
Journal ArticleDOI
A New Coil Structure to Reduce Eddy Current Loss of WPT Systems for Underwater Vehicles
TL;DR: A coil structure utilizing two transmitter coils placed symmetrically adjacent to each side of the receiver coil, termed a 1 × 1 ×-1 structure, yields improved power transfer efficiency and is very useful in underwater vehicle applications.
