FIELD: transportation.
SUBSTANCE: invention relates to electric traction systems of vehicles with supply from internal power supply sources. Traction locomotive converter comprises n channels of power conversion. Converter channels are formed by a charging-discharging converter, n converters, a device of excitation current control, a source of supply from an external network and/or a converter of diesel generator frequency. Besides, the charging-discharging converter, n converters, the device of excitation current control, the source of supply from the external network and/or the converter of diesel generator frequency are connected to each other. Moreover, the charging-discharging converter, n converters, the device of excitation current control, the source of supply from the external network and/or the converter of diesel generator frequency contain software making it possible to control, protect and perform diagnostics of the internal channel.
EFFECT: increased energy efficiency of a locomotive.
