摘要

An apparatus (100) for producing tractive effort, the apparatus (100) comprising: an energy source (110) adapted for generating a high DC voltage (120); a motor drive (130) adapted for generating a motor voltage (140) from the high DC voltage (120); and a motor (150) adapted for producing the tractive effort from the motor voltage (140), the energy source (110) comprising: a heat engine (160) adapted for generating mechanical power (170) by burning a fuel; an alternator (180) adapted for generating an alternating voltage (190) from the mechanical power (170); a rectifier (200) adapted for rectifying the alternating voltage (190) and producing a low DC voltage (210); an energy battery (220) adapted for storing and delivering energy derived from the low DC voltage (210); and a traction boost converter (230) adapted for boosting the low DC voltage (210) to produce the high DC voltage (120), the motor drive (130) comprising: a power battery (240) adapted for storing energy and delivering power at the high DC voltage (120); and a traction converter (250) adapted for generating the motor voltage (140) from the high DC voltage (120) during motoring operation and for generating the high DC voltage (120) from the motor voltage (140) during braking operation.
