TRIAC and DIAC Explained Using a Ceiling Fan Regulator

Have you ever wondered how a ceiling fan regulator controls fan speed without wasting power as heat? In this video, we dive deep into the working of *TRIAC* and **DIAC**, the two key components used in modern electronic fan regulators. Starting from the basics of AC waveform, we will explore how a TRIAC works as a bidirectional switch, how a DIAC provides reliable triggering, and how phase angle control is used to regulate the power delivered to the fan. We will also analyze the complete fan regulator circuit, capacitor charging process, triggering mechanism, waveform chopping, and the advantages of TRIAC-based regulators over old resistive regulators. Whether you are a beginner in electronics, an engineering student, or someone curious about how everyday electrical devices work, this video will help you understand the complete working principle of a ceiling fan regulator from the ground up. circuit - https://circuitdigest.com/electronic-... 📌 Topics Covered: What is a TRIAC?
