DEVICE FOR UNDERWATER OBJECT STORAGE BATTERY CHARGING Russian patent published in 2016 - IPC H02J7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Device for storage battery charging is arranged in three structural units. In first unit, installed aboard ship, is first controlled voltage rectifier. In second unit, made with possibility of immersion under water, arranged capacitor, single-phase self-contained voltage inverter with control unit, as well as separately made transformer primary winding. In third unit, to be installed on underwater object, are arranged separately made transformer secondary winding, second rectifier, smoothing reactor, as well as device output voltage measuring converter. Device additionally includes second capacitor, connected in series to transformer secondary winding, third capacitor, connected to second rectifier output terminals, first and second temperature measuring converters, which inputs are connected with autonomous inverter heat-generating components and wire of transformer primary winding, respectively, and outputs are connected to autonomous inverter control unit inputs, switch, connecting one of second rectifier outputs and one of device two output terminals, whereto charging storage battery is connected.

EFFECT: such device design allows to improve reliability and quality of underwater facility storage battery charging process from ship AC network.
