摘要

针对水下航行器等海洋机电设备传统供电方式存在的水下电缆供电活动范围受限、蓄电池供电工作时间受限等问题,设计基于双E类功放电路的水下大功率无线供电装置.该装置采用磁耦合谐振式无线电能传输技术,同时,相关电路参数以Raab条件为基础进行设计,使双E类功放电路MOSFET开关管实现ZVS、ZDS软开关导通.通过Multisim电路仿真软件,建立该装置无线供电电路模型,可实现千瓦级的无线供电功率,无线电能传输效率达94.5％,距离为20 cm.仿真结果验证理论设计可行.%For the underwater vehicle and other marine electrical equipment, the traditional way of power supply exist some problems, such as underwater cable power supply and range of activities is limited, the battery-powered, working time is limited and etc, An underwater high-power wireless power supply device based on double E-type power amplifier circuit was designed. Based on magnetic coupling resonance-based wireless power transfer technology, the circuit-related parameters was designed by u-sing Raab conditions, so as to make MOSFET in double Class E amplifier circuit operate in ZVS, ZDS soft-switch.The wireless power supply circuit was simulated by Multisim, verifying that the wireless power supply power is over 1000 W, and the wireless power transfer efficiency is 94.5％, the distance is 20 cm.
