Design of 600V IGBT for Home Appliance Smart Power Module

摘要

600V IGBTs are designed and characterized for novel 3-phase home appliance smart power modules so called SPMs. The SPM series are very functional, compact and cost effective. As the SPMs contain high side and low side gate drive IC with IGBTs, smooth switching waveforms of IGBT without EMI noises during switching periods are indispensable as well as low conduction and switching losses. Device characteristics such as Vce,sat of 2.0V at Jc=160 A/cm~2, Eoff of 25 uJ/A @ Vcc=300V, SCWT longer than 10 usec are obtained. In addition, good linearity and low dispersion of current sensing IGBT were also designed for the short circuit protection.
