How Does an SCR Work? | Construction & Applications

In this video, we explain the construction and working of SCR (Silicon Controlled Rectifier) step by step with diagrams. SCRs are one of the most important power electronic devices, widely used in rectifiers, inverters, and motor control circuits. What you’ll learn in this video: - Structure and layers of an SCR (PNPN device) - Working principle of SCR - Applications in power control and electronics This video is part of our Semiconductor Devices Module under Basic Electrical & Electronics Engineering, designed for 1st year engineering students preparing for KCET, JEE, and GATE.
