IXYS NEW Dual High Power Thyristor Modules

This new dual phase control thyristor module provides high power, pressure contact modules up to 6500V. Designed to convert AC to DC for medium voltage applications, modules operate at line frequencies where keeping conduction losses low are important. Higher voltage capability enables the use of standalone modules rather than requiring series connected devices to handle higher voltages. It is ideal for applications such as medium voltage motor control and soft starters.

Mitsubishi Electric MOSFET

MOSFET (Metal Oxide Semiconductor Field Effect Transistor) has a proven record of providing low current and low withstanding voltage in power devices that require high-speed switching, voltage driving and low loss. The use of a trench gate structure, enabled by submicron technology, radically reduces the low on-resistance (the resistance value in the region where the drain current flows between the drain and the source) compared to a planar structure.

Insulated-gate bipolar transistors and diode dies

Hitachi ABB Power Grids' 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. The newly introduced 1700 V SPT++ chipset is the world’s first 1700 V chipset that offers an operative junction temperature of up to 175 °C. This allows the module designer to increase the power density of power modules considerably.
