METHOD FOR SUPPLYING ELECTRICITY TO CONSUMERS IN A VEHICLE AND SYSTEM FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC B60L1/00 

FIELD: electric engineering, vehicle engineering.

SUBSTANCE: in accordance to electricity supplying method, direct current consumers are supplied from direct current source, and for alternating current consumers, stationary alternating current network or autonomous alternating current power supply are used alternatively. In standard operation mode of vehicle, an inverter, connected to direct current source, is used as autonomous alternating current power supply. Alternating voltage is transformed and then rectified. Rectified voltage is added to voltage of direct current power source, which is then inverted and its level is adjusted. Inverted total or transformed voltages are supplied to consumers of alternating current alternatively. In stationary mode of vehicle operation, voltage of stationary alternating current network is transformed and transformed voltage is supplied to alternating current consumers of vehicle. Transformed voltage is also rectified using aforementioned inverted, made in reversible form, and rectified voltage is supplied to direct current consumers. Also a system for realization of method is suggested, containing an inverter connected to direct current source, transformer, intermediate rectifier and second inverter, inverting total direct current voltage to alternating current voltage, which is supplied to alternating current consumers through a commutator.

EFFECT: increased reliability of electric supply system, lower energy costs.
