A silicon controlled rectifier or semiconductor controlled rectifier is a four layer solid state current controlling device. Three phase bridge scr control of load. It is mainly used in the devices for the control of high power.
It is mainly used in the devices for the control of high power.
A three phase controlled rectifier circuit built with scrs without pulse transformers or triggering circuitry shown would look like the figure below. The name silicon controlled rectifier is general electric s trade name for a type of thyristor. Three phase bridge scr control of load. The silicon controlled rectifier scr is the most important and mostly used member of the thyristor family.
