MODULAR POWER SUPPLY SYSTEM Russian patent published in 2018 - IPC H02J9/00 

FIELD: electrical engineering.

SUBSTANCE: system has a built-in telecommunications module that provides remote control and monitoring. In addition, any of the modules of the system can be used as a portable AC power source. Modular power supply system comprises at least one module comprising a module docking unit, remote control means, a connector for connecting an alternating current source in the form of an electrical network or a generator, and a connector for connecting a direct current source made in the form of solar panels, connectors for connecting to an AC load, made in the form of a power connector and two outlets, and connectors for connecting to a DC load, made in the form of four USB or similar outputs. In this case, the connector for connecting the AC source through the switching unit of the electric power supply from the AC source is connected to the connectors for connecting to the AC load and with the AC to DC converter, and a connector for connection of a direct current source through a series-connected unit for selecting the maximum power from solar panels and the unit for detecting the voltage drop from the DC source is connected to the battery charging unit and to the first DC-DC converter to increase and stabilize the voltage. Battery charging unit through the battery management unit (BMU) is connected to a battery pack which is connected to a first DC-DC converter, and the first DC-DC converter is connected to the connectors for connection to the AC load through the inverter with the function of switching off the supply of DC electric power and with connectors for connection to a DC load through a second DC-DC converter, reducing the voltage.

EFFECT: increased stability and reliability of the modular power supply system.
