Abstract
A pulse controller for controlling the current supply to a plurality of d.c. loads through a respective main thyristor for each load is provided with digital circuitry operable to maintain the mark-space ratios of voltage applied to the loads in a relationship to one another which is set by a differential control circuit while the mark-space ratios are simultaneously varied in response to a drive control circuit. The controller may be used to control two d.c. motors respectively driving right-hand and left-hand traction wheels of a battery-electric vehicle, to provide differential drive when the vehicle negotiates a curve.
