ALTERNATIVE SYSTEMS FOR RAPID-TRANSIT PROPULSION AND ELECTRICAL BRAKING

The need for rapid transit is stimulating further development in the technology and equipment for propulsion and electrical braking. Although the traditional cam-controller equipment is being improved, control systems based on thyristors have some advantages over it, achieved at a cost in weight and complexity of the control equipment. The thyristor approaches overcome 2 basic problems of cam-controller equipment: the need for continual maintenance on the cam switch contacts and the power losses incurred when voltage is controlled by resistors.
