Chopper Drives. The high-speed switch (chopper) characteristics of phase-controlled rectifiers (thyristors) can be used to create adjustable-speed dc drives. A constant-voltage rectifier or a dc bus is used as the incoming supply. When the first thyristor is turned on by a reference-level signal, the dc motor is connected to the constant-voltage bus. When motor speed rises above the reference level, a second thyristor is turned on, shutting off the first, and the motor... [Pg.659]
