🔍 Key Concepts

• Silicon controlled rectifier (SCR) is a type of thyristor used primarily for controlling and rectifying power in high-voltage or high-current circuits • Think about where you need controlled DC from AC, or controlled power flow, especially in propulsion or large motor drives • Compare what typical components are used for sensing, voltage reference, and filtering AC hum vs. power control

💭 Think About

• Which option involves controlling a large amount of electrical power, such as to a motor or heavy load, rather than just sensing or small-signal functions? • Which devices are normally used as voltage references and sensor elements—are those usually SCRs, zener diodes, or photocells? • In which application would you need to vary or regulate power delivery using phase control of AC, rather than just smoothing or detecting voltage?

✅ Before You Answer

• Identify which choice deals with power control to a major load (like a propulsion motor) rather than small control signals • Recall that an SCR is not primarily a sensor or reference device; it is a controlled rectifier/switch for power circuits • Eliminate any option that mainly describes filtering or smoothing AC ripple, which is more associated with capacitors and filters, not SCRs
