1. It is widely used in the triggering circuits for silicon controlled rectifiers . 2. Some sources define silicon-controlled rectifier ( SCR ) and thyristor as synonymous. 3. The controlled rectifier input allows power factor correction. 4. My question is concerned wthh silicon controlled rectifiers . 5. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. 6. TRIACs are a subset of thyristors and are related to silicon controlled rectifiers ( SCRs ). 7. Both silicon-controlled rectifiers ( SCR ) and TRIACs are members of the thyristor family. 8. This psychedelic lighting was made economical by the development of the silicon-controlled rectifier ( SCR ). 9. When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. 10. Two 9-volt SCR ( silicon controlled rectifier ) as the switch to trigger the filaments to detonate the bomb.
