Design of Snubbers for Power Circuits

be some residual inductance which may cause a ringing voltage spike at turn-off as shown in figure 3B. The most common reasons for using a snubber are to limit the peak voltage across the switch and to reduce the switching loss during turn-off. RC snubber design

MOSFET/IGBT DRIVERS THEORY AND APPLICATIONS

point of view of circuit analysis, it is an RC Circuit. After time t 1, as the Gate-to-Source voltage rises above V GS(th), MOSFET enters linear region as shown in Fig. (2). At time t 1, Drain current commences, but the Drain to Source voltage V DS is still at V DD. However, after t 1, I D builds up rapidly. As can be seen in Fig. (3B), from ...
