ABB Semiconductors’ SPT (Soft Punch Through) chipsets and its improved versions with lower losses (SPT+ and SPT++) are available at 1200 and 1700 volt. They feature highest output power per rated ampere due to a moderate chip shrinkage and thus larger die area.
Typical applications for 1200 volt are power converters for industrial drives, solar energy, battery backup systems (UPS) and electrical vehicles. Applications for 1700 volt include industrial power conversion & drives, wind turbines and traction.
ABB’s newly introduced 1700 V SPT++ chipset is the world’s first 1700 V chipset that offers an operational junction temperature of up to 175 °C. This allows the module designer to increase the power density of power modules significantly.
