摘要：
This paper describes an analysis and optimisation of a turn-off snubber suitable for application in IGBT's circuits. The optimisation procedure limits 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 experimentally.
