NettetThyristor or SCR is mainly used for controlled rectification and to control the power supplied to any load such as in lamp dimming, regulators and motor control.. The Thyristors are used for managing and controlling the large power, therefore they are rated in Kilowatts. and they are bulkier in size as compared to a transistor. NettetTHYRISTOR BASED TECHNIQUES OF DC MOTOR SPEED CONTROL A separately excited DC motor fed through single phase half wave converter is shown in figure 3. Single phase half wave converter feeding a DC motor offers only one quadrant drive. Such type of drives are used up to about 0.5 kW DC motor.
