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.

L'invention concerne un appareil (100) conçu pour produire un effort de traction, qui comprend une source d'énergie (110) qui génère une haute tension CC (120); une commande de moteur (130) qui génère une tension de moteur (140) à partir de la haute tension CC (120); et un moteur (150) qui produit l'effort de traction à partir de la tension de moteur (140). La source d'énergie (110) comprend un moteur thermique (160) qui génère une puissance mécanique (170) en brûlant un carburant; un alternateur (180) qui génère une tension alternative (190) à partir de la puissance mécanique (170); un rectificateur (200) qui rectifie la tension alternative (190) et qui produit une basse tension CC (210); une batterie à énergie (220) qui stocke et qui délivre l'énergie dérivée de la basse tension CC (210); et un convertisseur amplificateur de traction (230) qui amplifie la basse tension CC (210) afin de produire la haute tension CC (120). La commande de moteur (130) comprend une batterie à puissance (240) qui stocke de l'énergie et qui alimente en puissance la haute tension CC (120); et un convertisseur de traction (250) qui génère la tension de moteur (140) à partir de la haute tension CC (120) lors du fonctionnement de moteur, ainsi que la haute tension CC (120) à partir de la tension de moteur (140) lors du fonctionnement de freinage.
