A consecutive parameter extraction technique for IGBT compact model

摘要

A consecutive parameter extraction technique describes the fitting target related parameters for Insulated-gate bipolar transistor (IGBT) model. The IGBT model has been represented by a couple of simplified equivalent circuits. Using simulated data for a trench-type IGBT as reference the performance of compact model IGBT is compared to an IGBT macro model. Due to physics based modeling, parameter extraction with the compact model is fast. With very less extraction effort, the compact model fits the dc current and capacitance characteristics accurately.
