Abstract

An insulated gate bipolar transistor(IGBT) is a MOS gate turn on/off bipolar transistor which combines the attributes of the MOSFET and bipolar transistor. Because of its limitation of power capability compared to thyristor or GTO, some parallel connection of IGBT has been studied to improve the limitation of current capabillity. In this paper, the switching effects from the unbalance of internal parameters of IGBT and the turn-off snubber characteristics are investigated using SPICE program.
