ELECTRIC TRACTION DRIVE OF VEHICLES Russian patent published in 2017 - IPC B60L11/06 B60L11/18 

FIELD: electricity.

SUBSTANCE: electric traction drive of vehicles contains a thermal engine, traction AC alternator connected to the input of a power rectifier via its three-phase winding. The rectifier output is connected to electric DC traction motors through train contactors. The traction drive is supplied by a battery through two gate-insulated bipolar transistors when the thermal motor is disconnected. Wherein the positive battery clamp is connected to the armature of the first pair of traction motors by means of the first and second additional contactors. The armature of the second pair of traction motors is connected to the collectors of the first and second bipolar transistors by means of the third and fourth additional contactors. The emitters of the first and second bipolar transistors are interconnected and connected to the negative clamp of the battery.

EFFECT: increased reliability of the traction drive.
