ONBOARD POWER SUPPLY Russian patent published in 2023 - IPC H02J7/34 

FIELD: electrical engineering.

SUBSTANCE: onboard power supply source contains at least two intermediate voltage converters, which are configured to be connected to consumers, and one of them is connected to the storage battery, to which the bidirectional voltage converter is connected. The source additionally contains an input DC/DC converter and/or an input three-phase rectifier. Input DC/DC converter and/or input the three-phase rectifier is/are connected to the intermediate DC bus. Between the battery charging converter and one of the converters generating voltage for consumers, a bidirectional voltage converter is connected, configured to generate an output voltage for consumers from the battery voltage. Intermediate converter, made with the possibility of connection to the storage battery, together with the bidirectional voltage converter, are made with the possibility of obtaining information from the current sensor located in the battery charge circuit.

EFFECT: ensuring versatility in terms of permissible input supply voltage and increasing specific power while maintaining the function of uninterrupted operation and redundancy.
