IGBT driver chipset for high power applications

Power electronics systems in the 600 V to 1700 V range are commonly used in motor drive, power supply and power conversion applications. An integrated chipset is presented for application in IGBT high power systems. It has flexible controller ICs on the primary side and strong driver ICs on the secondary side. The whole system is arranged so that pulse transformers provide physical potential separation and the voltage is scalable between 600 V and 1700 V at currents from 20 A up to 3000 A. The option to use opto-couplers and fiber optics instead of pulse transformers extends the chipset's applicability.
