Snubber Circuits_CAPT_講義
Overview
Snubber circuits are for power devices’ protection.
diode, thyristors: RC to alleviate transients of reverse recovery.
Transistors:
RCD: limit dv=dt at turn-off.
RLD: limit di=dt at turn-on.
Re-shape the switching loci and reduce the switching losses across the power
device. |
