Disadvantages of SCR
- Gate triggering can be sensitive to noise: The door setting off instrument of SCRs can be delicate to electrical commotion, so legitimate assurance and separating might be vital.
- Unidirectional conduction: SCRs lead current in only one bearing, making them unacceptable for applications that require bidirectional control of current.
- Potential for voltage spikes: At the point when a SCR is switched off, it can produce voltage spikes in the circuit, which might require extra defensive parts.
- Lack of inherent turn-off capability: When a SCR is set off (turned on), it will stay in the “on” state until the ongoing through it dips under a specific limit or is switched. This can be a constraint in certain applications.
- Limited frequency response: SCRs are not appropriate for high-recurrence applications because of their mood killer attributes and entryway control constraints.
- Higher cost compared to some alternatives: At times, SCRs might be more costly than other semiconductor gadgets, like MOSFETs or IGBTs, for explicit applications.
Silicon Controlled Rectifier
The SCR or thyristor is one type of semiconductor device and using in high-power switching applications is exceptionally planned. The working of this device should be possible in a switching mode only and acts as a switch. When the SCR is triggered by its gate terminal into the transmission, then it will supply the current constantly. While planning a SCR or Thyristor circuit, exceptional focus ought to be expected for enacting the circuit. This article examines various techniques for SCR setting off or SCR turn ON strategies or setting off of Thyristors. There are different setting off strategies are accessible in light of different substances which incorporate temperature, voltage, and so on.
