T-type IGBT module with new voltage class authentic RB-IGBT for DC-1000V solar inverter application

This paper describes newly developed T-type full-leg IGBT modules, specifically designed for mega-solar inverter application of higher DC-input voltage, such as DC 1000V input. The newly developed 900V voltage class authentic RB-IGBTs are installed in the power module, which have significant advantages in switching performance when compared to the alternative method 1200V standard IGBT and reverse blocking diode cascade. The 1200V-900A full-T-leg high power IGBT module demonstrations will be discussed.
