3.4 BJT and IGBT basics
2021년 3월 26일
In this lecture, we will learn:
- BJTs rely on minority carriers to switch on and off.
- They can have extremely low resistance but suffer from minority-carrier effects like reverse recovery.
- IGBTs use an insulated gate and have no base current.
- IGBTs are popular in very high power applications at relatively low switching frequency (~0.1 – 10 kHz).
