Phase controlled thyristor pdf

In its simplest form, phase control can be described by considering the half-wave thyristor circuit. In half wave Single phase controlled rectifier only one SCR is employed in the circuit. It included in between the AC source and the load. The performance of the controlled rectifier very much depends upon the type and parameters of the output The control terminal of the thyristor is named the gate and it is connected to the p-type layer located next to the cat hode.

However, the resultant of two related phase currents creates the TCR line current.

The device name comes from the similarity of operation with the gas triode: thiratron transistor. Because the thyristors are mainly used in the controlled rectifier structures, the technical literature calls them as SCR (Semiconductor The thyristor is a power semiconductor device with the control terminal called grid or gate (G).
