摘要
Abstract
A composite control method was proposed to achieve both maximum efficiency tracking and adjustable output power for unmanned undersea vehicle wireless charging systems.First,the factors affecting the power transmission efficiency of the underwater magnetically coupled wireless power transfer(MC-WPT)system were analyzed.Considering the eddy current loss in the coupling mechanism within the seawater environment,the equivalent eddy current resistance was obtained through magnetic-field and circuit co-simulation,and the optimal load was calculated.Second,a Cuk converter was cascaded on the receiver side for impedance matching to achieve maximum efficiency tracking,while a wide power range was regulated by controlling the phase-shift angle on the transmitter side.The two control loops for efficiency and power operated independently.Finally,a system simulation model was constructed,and an experimental prototype was built to validate the theoretical analysis and the proposed method.The experimental results show that the maximum efficiency tracking method improves the efficiency under various load conditions.For instance,at 2 kW output with a 5 Ω load,the system efficiency increases from 84.8%to 93.1%.When the input voltage varies,the output power is regulated from 1 to 3 kW while maintaining maximum efficiency by adjusting the phase-shift angle.Both simulation and experimental results demonstrate that the system can operate consistently with high efficiency and adjust the output power in real time according to demand.关键词
