Abstract :
This paper describes an analysis and of a turn-off snubber suitable for application in power IGBT circuits. The optimisation procedure limits the transistor temperature rise to an acceptable value (rather than minimising it) and minimises the reset time of the snubber. A simple design procedure is presented for snubber component calculation. The analytical results are verified by simulations and experiments
