FIELD: transport.
SUBSTANCE: invention refers to control of losses suppression in electric power supply system and can be used in vehicles. Electric power supply system contains the first voltage converter, the second voltage converter, control unit. The first voltage converter is located between the first power accumulating device and loading device for voltage conversion. The second voltage converter is located between the second power accumulating device and loading device for voltage conversion. The vehicle includes power accumulating device, electric power supply system, exciter, electric motor. The method includes the first stage, the send stage and the third stage. In the first stage, necessary power required from electric power supply system is compared with reference value. In the second stage, the first and the second voltage converters are operated so that one of these two voltage converters is working and the other voltage converter stops when required power is less than reference value. In the third stage, the first and the second voltage converters are operated so that first and the second voltage converters are working when required power is equal to or exceeds reference value.
EFFECT: lowering losses in electric power supply system.
