Hitachi Energy’s SPT (Soft Punch Through) chipsets and their improved versions with lower losses (SPT+ and SPT++) are available at 1200 V and 1700 V. They feature highest output power per rated ampere due to a moderate chip shrinkage and thus larger die area. Additionally to these well-established planar chip technologies, starting 2022, Hitachi Energy is adding a new chipset based on the recently developed Trench Fine Pattern (TFP) technology.
Typical applications for 1200 V are power converters for industrial drives, solar energy, battery backup systems (UPS) and electrical vehicles. Applications for 1700 V also include industrial power conversion & drives, wind turbines and traction converters.
