Abstract
In this paper, an underwater single-capacitor coupled wireless power transmission (USCC-WPT) system is proposed, which operates at 200 kHz and can transmit 1 kW of power at 1 m in seawater with an efficiency of 76%. The USCC-WPT system produces no eddy current losses in seawater, and the distance is increased compared to conventional inductive power transfer systems. The system proposed in this paper has a wide range of applications underwater. The load-independent constant voltage (CV) output and misalignment tolerance properties of the USCC-WPT system are analyzed and validated by an equivalent circuit model constructed from the stray capacitance. The 1 kW prototype demonstrates the feasibility of the USCC-WPT system proposed in this paper, while the system can work properly with 50 cm misalignment.
