Abstract

An Electric traction system having a separate excitation d.c. motor, an armature current control device, an excitation current control device, and between the motor armature and the d.c. supply source, several armature current switches (4-1...4-n) in parallel each made up of one or more transistors connected in parallel (30, 31 32). In order to avoid possible non-synchronous operation of the switches, each is connected with one terminal to an induction coil (5-1...5-n) and in series with the motor armature and with its other terminal to a diode (8-1...8-n) shunting said induction coil and the motor armature.
