200 kVA compact IGBT modules with double-sided cooling for HEV and EV

High power compact IGBT half bridge modules with a current rating of 300A and a blocking voltage of 650V using ultra thin IGBTs and diodes have been successfully developed with double-sided cooling capability. The wirebond-less package building block called COOLiR2DIE™ has a small area of 28.5 mm × 16 mm with a power rating 200 kVA, This is the most compact IGBT package reported today. A low on-state voltage of 1.6V at 300A is achieved in the wirebond-less package. The combination of lower on-state voltage and larger heat exchange area due to the solderable front metal (SFM), increases the IGBT module current carrying capability by 30%.
