STATE OF THE ART OF DV/DT AND DI/DT CONTROL OF INSULATED GATE POWER SWITCHES

Abstract : IGBT and MOSFET power switches are commonly used in power converters. MOSFET for middle power and IGBT for high power converters : gate drive circuits are used to drive such components. Some applications need to control dv/dt and di/dt from power switches to reduce electromagnetic emissions. New solutions have been introduced and tested since 1990 (conresponding to the maturation of IGBT technology). This article is about a state of the art of di/dt and dv/dt methods. The authors propose original solutions with simulations and experimental results on 1200A-3300V IGBT modules.
