Fast-switching IGBTs

14 October 2009 Power Electronics / Power Management

Ixys has extended its XPT IGBT module product range towards packages with higher power density and smaller footprints. The MiniPack2 and Mini E1-Pack are updated with the successful XPT and Sonic diode combination in the range of 10 to 50 A with 1200 V collector emitter voltage. The XPT technology is Ixys’ newest generation of short-circuit rated high-voltage IGBTs with fast switching and low conduction loss performance.

The new module portfolio targets applications that include 5 to 30 kVA solar inverters, motor drives and power supplies where the use of Ixys’ own DCB (direct copper bonded) ceramic technology combine with the latest generation IGBT and diode to provide a UL certified solution. The MiniPack2 simplifies the assembly process due to specially designed mounting clips, ensuring faster assembly times. The DCB ceramic is also used as the base plate, which eradicates the need for an external copper base plate and allows 2,5 kV terminal to base isolation.

The XPT IGBTs have a positive forward voltage coefficient, which enables parallel operation, thus facilitating scaling up the current capability with the use of multimodule systems. Ixys’ concentration on reliability is continued with the XPT rugged behaviour demonstrated by power turn-off testing (RBSOA) being specified at three times the nominal current value.

The XPT IGBT and Sonic diode combination in the ‘Mini’ modules are available in converter brake inverter (CBI) module and six-pack topologies. The diode bridge input rectifier with break chopper supplements the 3-phase inverter six-pack stage in the CBI configuration. Customised configurations are also possible on request.
