Power Electronics | Lecture 6 | SCR Basics & Half-Wave controlled Rectifiers

In this lecture, we discuss the fundamentals of Silicon Controlled Rectifiers (SCR) and their application in Half-Wave Phase Controlled Rectifiers. We cover the internal structure of SCR, its VI characteristics, and compare it with traditional diodes. You'll also learn about key data sheet specifications like latching and holding currents, and how SCR operates with resistive (R) load. What you will learn: Classification of Rectifiers (Controlled vs. Uncontrolled) Internal structure and Two-Transistor Model of SCR SCR VI Characteristics: Forward and Reverse Blocking Modes Key Specifications: Latching Current, Holding Current, and Peak Voltages Half-Wave Phase Controlled Rectifier with R and RL Loads Power Factor analysis and the role of Free-Wheeling Diodes #PowerElectronics #SCR #Rectifier #ElectricalEngineering #SCRCharacteristics #PhaseControl #EngineeringLecture #SiliconControlledRectifier #CircuitAnalysis #education #india #pakistan #engineeringlecture #university #engineering
