Protecting Diodes, Transistors, and Thyristors1

All power switching devices attain better switching performance if some form of switching aid circuit, called snubber, is employed.  Snubber activation may be either passive or active which involves extra power switches.  Only passive snubbers, which  are based on passive electrical components, are considered in this chapter, while active snubbers are considered in Chapter 9.  Fundamentally, the MOSFET and  IGBT do not require switching aid circuits, but circuit imperfections, such as stray inductance and diode recovery, can necessitate the need for some form of switch snubber protection.
