Description

This item was taken from the IEEE Conference ' A new intelligent gate drive module for IGBTs with high current drive capacity ' This paper presents a new intelligent gate drive module for IGBTs, with current drive capacity of over 6 amperes. The intelligent functions of this module include under voltage lockout protection and overcurrent protection with fault status annunciation. The module contains dual drivers which make it especially suitable for phase leg drive, and outputs bipolar signals so that the ""off"" status of the IGBT is ensured when the IGBT is required to be ""off"". It needs only a unipolar DC supply due to the built-in, well-regulated, and isolated floating power supply. This module features powerful functions, high performance, wide applications, and convenience of use. The detailed functions, operation, performance, and practical application issues are addressed.
