Snubber Circuit Design For Igbt

Snubber For Igbt

The effect on turn-off surge voltage is moderate. As opposed to the RC snubber circuit, a snubber diode has been added. This allows the snubber's resistance to increase and consequently avoids the IGBT load conditions at turn-on problem. Since the power dissipation loss of this circuit primarily caused by the snubber's resistance is much greater than that of a discharge suppressing snubber circuit, it is not considered suitable for high frequency switching applications. The power dissipation...
