DEVELOPMENT OF AN EXPERIMENTAL INVERTER-INDUCTION MOTOR DRIVE FOR RAILWAY TRACTION USE

The use of ac motor-inverter drives for railway vehicles has grown steadily. The development described is being carried out by an equipment manufacturer and a railway authority to check the practicalities of ac drives in railway conditions. The new train-borne equipment provided consists of twin inverters supplying traction motors of two types. Initially the dc input will come from an existing 25kV 50Hz controlled rectifier; later stages of test will use a 750V dc third rail supply. DC transistor choppers are used in advance of the current fed inverters. Dynamic rheostatic braking is provided over part of the speed range.
