TURN-ON SNUBBER The switching locus in the i Q -v Q plane for this transition is identical to the one shown on turn-off, except that the path is taken in the reverse direction. Once again, the transistor’s peak power and second-breakdown limits are exceeded.
TURN-ON SNUBBER The solution to the turn-on problem is the dual of the turnoff problem solution. A snubber, L s , is placed in series with the transistor. The waveforms are shown on the side.
