| Abstract |
The greater current and voltage handling capability of the modern power IGBT's require smart, high voltage isolated gate drive circuits, specifically designed to drive and protect them. The essential requirements of IGBT gate drive circuits in various operation conditions including bridge configurations have been analysed. Derivation of an isolated power supply, methods for over-current protection and the characteristics of the drive output stage are discussed and reliable solutions proposed. The proposed IGBT gate drive circuit is realised by discrete devices and has a low loss floating supply, a desaturation protection realising short circuit protection and current limiting and galvanic isolated fault feedback signal. |
