FIELD: transport.
SUBSTANCE: traction mechanism includes energy source (110) to generate constant high voltage (120); motor drive (130) to generate electromotive voltage (140) from constant high voltage (120); and electric motor (150) to create traction effort. Energy source (110) includes thermal engine (160) to generate mechanical energy (170) due to fuel combustion; alternator (180); rectifier (200) to rectify alternating voltage (190) and produce constant low voltage (210); energy battery (220) to accumulate and supply energy developed from constant low voltage (210); and intermediate traction converter (230) to increase constant low voltage (210) and produce constant high voltage (120). Motor drive (130) includes power battery (240) to accumulate energy and supply power at constant high voltage (120); and traction converter (250) to generate electromotive voltage (140) from constant high voltage (120) when driving and to generate constant high voltage (120) from electromotive voltage when braking (140).
EFFECT: increased efficiency and enhanced application of an electric traction system.
