COMBINED REGENERATIVE AND RHEOSTATIC BRAKE ON ELECTRIC RAILCARS POWERED BY DIRECT CURRENT

GEMISCHTE NUTZ -- UND WIDERSTANDSBREMSE BEI GLEICHSTROMTRIEBFAHRZEUGEN

Most rectifier-type sub-stations feeding catenaries are fitted with values that can allow current flow in both directions. This is impossible in a system with three-phase current. When catenary absorption capacity is variable, regenerative and rheostatic braking should be possible with electric brakes. In a braking situation the first step consists of increasing the braking current supply through a direct current converter; then this current is fed into the system by a diode for as long as the system can absorb it. If the circuit system does not require any power, there is a brake thyristor to activate and maintain a braking resistance right up until the end of the direct-current converter cycle.
