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 TWO 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. /DOT/
