🔍 Key Concepts

• Structure and operation of SCRs (Silicon-Controlled Rectifiers) • How bidirectional control of AC current is achieved in power electronics • Differences between DIAC, TRIAC, and field-effect transistors (JFET, MOSFET)

💭 Think About

• Which of these devices is specifically designed to conduct in both directions on an AC waveform while still being controllable from a gate? • Think about which options are power control devices used in AC dimmers and motor speed controllers, versus which are primarily transistor amplifying devices. • Which device is often described in textbooks as being equivalent to two SCRs in anti-parallel with a common gate connection?

✅ Before You Answer

• Eliminate devices that are not normally used as controlled AC power switches (look carefully at the transistor options). • Recall which of these components is commonly found in light dimmers and motor speed controllers for AC mains. • Verify which device’s basic model in theory is two SCRs connected in opposite directions sharing a gate.
