VEHICLE ELECTRICAL SCHEME, IN PARTICULAR OF THE RAIL VEHICLE Russian patent published in 2018 - IPC B60L9/04 B60L9/18 H02M3/07 

FIELD: vehicles.

SUBSTANCE: group of inventions relates to electrical traction systems of vehicles. Vehicle (10) electrical circuit includes an input side (20) for passing of the network voltage (V_N) provided by the power supply network (12) and consumption side (24) associated with the power supply consumer (25) in the vehicle. Electrical circuit comprises a voltage conversion unit (26) to provide the consumer (25) with a voltage (V_c) on the consumption side (24). Conversion unit (26) includes first section (28h) with operating potential (V_h), second section (28t) with operating potential (V_t) and charges transfer section (36), intended for the charges transfer from the first section (28h) to the second section (28t). Charges transfer section (36) includes element (38) connected to the pair of sections (28h, 28t) and switching unit (40) intended for the element (38) cyclic switching between the sections (28h, 28t). Together with the charges transfer section (36) element (38) the facility (46) defines resonant frequency. Switching unit (40) control unit (42) is designed to operate at a resonant frequency. Also claimed is a vehicle, in particular, a railway vehicle.

EFFECT: technical result consists in the power supply provision to consumers on a vehicle with different network voltages.
