IGBT Latch-Up Explained & Static V–I Characteristics

Welcome to Circuitadda!
This is the 15th video in the series Thyristorized Power Control (Power Electronics).

In this lecture, we explain:
✅ What is Latch-Up in IGBT?
✅ Causes and Effects of IGBT Latch-Up
✅ Methods to Prevent Latch-Up in Power Circuits
✅ Static Characteristics of IGBT
✅ V–I Characteristics and Operating Regions

This lecture is highly useful for students of Electrical & Electronics Engineering preparing for GATE, ESE, and university-level exams.
It provides a clear understanding of IGBT behavior under static conditions and the critical issue of latch-up, which is important in power switching applications.
