IXYS UK IGBTs
IXYS UK's IGBTs are a pioneer of Press-Pack IGBT technology, they offer a large range of class leading devices with voltage ratings of 1.7kV (900V DC link), 2.5kV (1.25kV DC link) and 4.5kV (2.8kV DC link).
The production of these devices is free from wire and solder bonds which all but eliminates the problems of mechanical fatigue associated with conventional modules. Internal stray inductance in both the gate connections and emitter connections is vastly reduced when compared to conventional modules leading to improved ruggedness and short circuit behaviour, which is further enhanced by direct cooling of the emitter side of chip.
IXYS devices feature state-of-the-art punch through (PT) process, which yields exceptional values VCE(sat) and quiet switching behaviour despite the high voltage ratings yet the devices feature a positive temperature coefficient making them suitable for reliable parallel operation. These devices are available with or without integral anti-parallel diode; a range of complimentary extra fast recovery diodes optimised for use with these IGBTs are available now.
IXYS UK press-pack IGBTs feature exceptional power cycling performance; typically an order of magnitude better than modules, making them highly suited to applications such as metals and traction drive systems where there are repeated cyclic power demands. Press-pack IGBTs have a stable short circuit failure mode which alongside safety benefits, makes them an ideal choice for medium and high voltage applications where series connection is required. Stable short circuit failure mode allows for the design in of n+ redundancy without additional bypass switches and costly explosion proof enclosures. Typical examples include HVDC, FACTs, Active VAr controllers/compensators and medium voltage drives. In applications above 4MW press-pack IGBTs offer exceptional power density, far exceeding that achievable with comparable modules in multi-level/MMC based converters.
IXYS UK's press-pack IGBTs are largely backwardly compatible with standard 2.5kV and 4.5kV GTOs in many applications such as AC drives. This makes these parts a simple and economical path to upgrade or refurbish equipment that previously used GTOs, such as locomotives or medium voltage drives. They are suitable for all cooling options including direct liquid immersion. Complementary gate drives, mounting clamps and passive components are available.
