Embodiment Construction

[0025] Such as figure 1 As shown, the traction train 1 essentially comprises a battery 2 whose output terminals 3, 4 are connected to a static converter 5 ensuring the inverter function. This inverter 5 comprises an input capacitor 6 and different arms 7 each comprising two static switches, between which an output terminal 8 is connected. When this inverter is properly controlled, the voltage presented between the output terminals 8 forms a three-phase voltage system. This inverter 5 supplies an electric motor comprising three stator windings 11 , 12 , 13 . The output terminal 8 of the inverter is connected to one of the terminals 14 , 15 , 16 of each stator winding 11 , 12 , 13 . The phase return terminals 17, 18, 19 of the stator windings 11, 12, 13 are themselves connected to a terminal block 25 which will be connected to an external power supply.

[0026] exist figure 1 In the form shown, the three phase return terminals 17 , 18 , 19 of each stator winding are connecte...

Abstract

The invention relates to an electric traction chain (1) for an automobile, including: an onboard rechargeable power source (2); a static converter (5) capable of generating a three-phase voltage system connected by input to said rechargeable power source (2); a three-phase electric motor (10) supplied with power by the three-phase voltage system generated by the static converter (5); and wherein an external electric power source (35) is connectable to the stator windings of the motor to enable recharging of the onboard power source across the static converter (5). The electric traction chain is characterized in that the motor (10) is synchronous with separate excitation, for which the power supply to the rotor (23) is cut off during the recharging phases.

Description

technical field [0001] The present invention relates to the field of motor vehicles, and more particularly vehicles comprising electric traction trains. [0002] Rather it is aimed at achieving a specific arrangement capable of improving the charging times of the accumulators delivering the traction power. Background technique [0003] In general, vehicles incorporating electric traction trains include batteries designed to provide the power required for traction functions. This battery supplies power to the electric motor via a static converter. The function of these converters is to generate a system of alternating voltages, advantageously three-phase voltages, which are applied directly to the electric motor. This type of converter thus operates as an inverter and thus delivers a multi-voltage system whose amplitude and frequency are controlled to deliver the required torque. [0004] However, one problem that has been identified with vehicles with electric traction tr...
