Abstract
An IGBT modeling method includes creating piece-wise line functions describing a collector-emitter voltage v, a collector current iand a gate-emitter voltage vof the IGBT during a switching-on transient based on an internal structure of the IGBT and transient processes of the IGBT. The IGBT modeling method further includes creating piece-wise line functions describing the collector-emitter voltage v, the collector current iand the gate-emitter voltage vof the IGBT during a switching-off transient based on the internal structure of the IGBT and the transient processes.
