Abstract

The application is principally to the control of traction motors where smooth acceleration is required. The rectifier (2) comprises typically three bridges (21, 22, 23) connected in series on the d.c. side and supplied from three separate secondary windings (12, 13, 14) on the transformer (1) which has a single primary (11). The controlled bridges are switched sequentially, one to give a ramp and the remainder in blocks to build up a steadily rising voltage across the motor (3). To avoid sudden current pulses the block is not switched in until the ramp voltage, plus any block already in, is slightly higher than the incoming block voltage. The voltage drop due to commutation from the outgoing rectifiers to the incoming one is thus compensated.
