METHOD AND SYSTEM FOR SUPPLYING DIRECT CURRENT CONSUMERS WITH A POWER SUPPLY SOURCE BASED ON RENEWABLE ENERGY RESOURCES Russian patent published in 2021 - IPC H02J3/28 

FIELD: electrical power engineering.

SUBSTANCE: power supply system includes a rectifier, a power supply source based on renewable energy resources linked with a direct current consumer. The system is equipped with a power supply line with a power supply source based on traditional energy resources and a rectifier at the output. The line is connected in parallel to the line with the power supply source based on renewable energy resources. A voltage converter is included in one or both lines of power supply sources. The nominal direct current voltage at the output of the power supply line based on renewable energy resources is set higher than the nominal voltage at the output of the parallel line of the power supply source based on traditional energy resources.

EFFECT: provided reliable direct current power supply to consumers without electrical losses and economic costs.
