GUARANTEED POWER SUPPLY DEVICE WITH CONTROLLED STRUCTURE Russian patent published in 2024 - IPC H02J7/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to high-power storage batteries control devices as part of autonomous power supply systems of critical consumers. Device of guaranteed power supply with controlled structure contains set of accumulator batteries, control system, controlled keys of the first group, controlled keys of the second group, which additionally includes controlled keys of the third group in the parallel connected accumulator batteries, at that, inputs of the controlled keys of the third group are directly connected to the positive terminals of the batteries, with inputs of the controlled keys of the first group and with inputs of the controlled keys of the second group, and outputs of controlled switches of the third group are connected to inputs of controlled switches of the first group, which are connected to negative terminals of batteries.

EFFECT: disclosed is a guaranteed power supply device with a controlled structure, which enables to change the configuration of the structure of a set of storage batteries for various connections to each other, depending on the operating mode, the presence of a certain number of failed storage batteries, voltage imbalance between them, as well as when the mains parameters change.
