The present invention provides an efficient wireless coupling power supply structure of an underwater device. An AC-DC or DC-DC source transformation circuit is divided into two independent parts consisting of a source transformation high-frequency excitation circuit and a source transformation high-frequency coupling circuit, corresponding inductance coil and magnetic core are divided into two parts with the two parts of function circuits, and the two parts are sealed by a water-tight box processed by two high-insulativity non-magnetic materials, and high-frequency signal coupling on the coiland electromagnetic wave wireless coupling complete wireless energy transmission of the power supply. A general single magnetic core coil coupling mode is changed to a dual-magnetic core inductance coil wireless coupling mode, wireless coupling between close high-frequency inductance coils achieves energy wireless coupling transmission between the two parts of circuits so as to achieve separation, docking and combination of joints at two ends and change the power supply connection of the underwater device to a wireless coupling power supply mode.
Description
technical field [0001] The invention relates to the technical field of energy transmission between power supplies of weak electronic equipment such as underwater equipment and underwater electronic control equipment. It is mainly used in the application of wireless power supply between underwater electronic equipment or between cables and electronic equipment. High-efficiency wireless coupling power supply structure for the lower equipment. Background technique [0002] No matter how high the reliability of underwater electronic equipment is, occasional failures may occur. Therefore, the maintainability design of electronic equipment is extremely important. Maintainability and maintenance convenience are the keys to low-cost operation of underwater equipment. The maintenance of underwater equipment carried out by dispatched engineering ships requires a long mobilization and demobilization time, and the equipment required for maintenance is complicated and expensive. Therefor...
