Thyristor – Controlied Motor Drives

Thyristor – Controlied Motor Drives Several factors have served to boost the use of thyristor-controlled motor drives, notably the high efficiency of thyristor converters (95-97%), the relatively small size, mass and time lag of thyristors, and the small power needed for the operation of thyristor controllers. A further advantage is that thyristor control offers a […]
