A new 3.3kV IGBT module, an advanced trench HiGT module, was developed. The current ratings of the advanced trench HiGT module can be increased by 20% from the present product type using new IGBT and Diode, and structural change with low thermal resistance and low internal stray inductance. To achieve low loss IGBT characteristics, an advanced trench HiGT(High Conductivity IGBT) structure is
