摘　　要：对IGBT的工作特性及存在的问题进行了深入探讨，详细介绍了用于提高大功率IGBT电桥的开关效率和安全性的ZVC／ZCC驱动模式。该模式利用IGBT的反向雪崩特性和电荷转移法实现IGBT的零电压切换和零电流切换，从而有效地抑制了器件内部的电流拖尾和自琐效应，大大地减小了开关损耗，提高了功率IGBT的工作效率和安全性。In this paper, some problems about IGBT's operation characteristics are discussed. A driving mode called zero voltage commutation and zero current commutation (ZVC / ZCC) technique with high efficiency and safety is introduced. By making use of removing charges and reverse avalanche of IGBT, zero voltage or zero current occurs during the commutation course of IGBT. It is very useful for reducing the effects of tailing and latching and improving the operation efficiency and safety.
