DEVICE FOR UNDERWATER OBJECT STORAGE BATTERY CHARGING Russian patent published in 2016 - IPC H02J7/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Device for storage battery charging is arranged in three structural units. In first module installed on ship, voltage rectifier is located. In second unit made with possibility of immersion under water, are arranged capacitor, single-phase autonomous voltage inverter with control unit, as well as separately made transformer primary winding and two temperature measuring transducers. In third unit, to be installed on underwater object, are arranged separately made transformer secondary winding, rectifier, capacitor, smoothing reactor, charging current regulator with control unit, as well as charging current and device output voltage measuring transducers. Device additionally includes voltage converter with control unit, delay unit and second current measuring transducer, wherein first rectifier output is connected to voltage converter input, which output of is connected to autonomous inverter input through second current measuring transducer, and temperature measuring transducers are acting on voltage converter through its control unit, wherein voltage converter with its control unit, delay unit and second current measuring transducer are arranged in second structural unit.

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