NettetThyristor is a four semiconductor layer or three PN junction device. It is also known as “SCR” (Silicon Control Rectifier). The term “Thyristor” is derived from the words of thyratron (a gas fluid tube which works as SCR) and Transistor. Thyristors are also known as PN PN Devices. En tyristor er en elektronisk komponent som består av fire lag halvledermaterialer, PNPN, og kan sees på som en styrbar diode. Symbolet er det samme som for en diode, men med en ekstra styreelektrode tegnet inn på siden (engelsk: gate). Om det ikke gis et strømsignal inn på styreelektroden, vil tyristoren sperre for strømflyt i begge retninger. Når en str… NettetA gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) semiconductor ...

Nettet21. okt. 2008 · The controlled (thyristor) rectifier provides a low-impedance adjustable 'd.c.' voltage for the motor armature, thereby providing speed control. Until the 1960s, the only really satisfactory way of obtaining the variable-voltage d.c. supply needed for speed control of an industrial d.c. motor was to generate it with a d.c. generator. NettetDescription. A DC motor represented by a simplified RL-E model is fed from an inductive three-phase source through a six-pulse thyristor bridge. A pulse generator synchronized on the source voltages provides the trigger pulses for the six thyristors. The converter output current is controlled by a PI current regulator built with Simulink® blocks. bananarama kerenNettetThe Thyristor Control of Motors can also be made to operate in the regenerative braking mode.

NettetThe voltage through thyristor starts increasing. Hence the motor speed gradually increases. Once the motor attains its full rated speed (at 0° firing angle), the thyristors are completely bypassed using a bypass contactor under normal operation. It increases the efficiency of the soft starter since the SCR stops firing.
