Abstract The TRENCHSTOP™ IGBT7 technology is based on the latest micro-pattern trench technology. It provides strongly reduced losses offering a high level of controllability [1]. This technology brings forward new challenges in compact modelling. Current IGBT compact models at Infineon are physics-based subcircuit representations in SPICE syntax. They were developed to run in the circuit simulator SIMetrix, and are manually calibrated. The aim of this work is to present advanced models for the micro-pattern trench IGBT implemented in Verilog-A language, addressing the challenges of compact models in terms of calibration accuracy, simulation run time, model robustness and portability to multiple simulators.
