POWER SUPPLY DEVICE FOR A REMOTE-CONTROLLED UNINHABITED UNDERWATER VEHICLE WITH DIRECT CURRENT ENERGY TRANSMISSION VIA AN SPC CABLE Russian patent published in 2021 - IPC H02J3/36 B60L9/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering for the power supply of underwater vehicles. The device contains a rectifier in the on-board part, the input terminals of which are connected to the electrical network of the ship through the input filter and the switching unit, DC converters and an SPC cable having positive, negative and zero wires connected by the supply end to the output terminals of the onboard part of the power supply device, and the receiving end to the input terminals of the underwater part, into each of the wires of which current and voltage sensors are inserted. According to the invention, the underwater part of the power supply device consists of the first underwater unit installed on a depressor park, the capacitors of the input filter of which, also made with a midpoint, are connected to the positive, zero and negative ends of the SPC cable wires and to a floating communication cable. The second and third underwater blocks are located on the underwater vehicle, connected to the input filter of the first underwater block through a winch of a three-core floating communication cable. The first underwater unit contains an autonomous inverter connected to a step-down transformer, the secondary windings of which are connected to the output underwater filters of the power supply buses of the consumers of the first group through the converter rectifier blocks. The second and third underwater blocks each contain a corresponding autonomous inverter connected to a step-down transformer, the secondary windings of which are connected through the converter rectifier blocks to the output filters of the power supply buses of consumers of the second and third groups, respectively. The second underwater consumer unit is connected to the input filter capacity between the positive and zero wires of the SPC cable, and the third underwater unit is connected between the zero and negative wires of the SPC cable.

EFFECT: increase in the fault tolerance of the system with an improvement in the quality of transients in consumer power buses.
