IXYS Corp. has expanded the XPT IGBT module product range towards higher power density, smaller footprint packages.

The MiniPack2 and Mini E1-Pack are updated with the XPT and Sonic diode combination in the range of 10A to 50A with 1200V 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 30kVA solar inverters, motor drives and power supplies where the use of IXYS' own Direct Copper Bonded (DCB) ceramic technology combined with the latest generation IGBT and diode to provide a competitive, UL certified, solution. The MiniPack2 simplifies the assembly process due to specially designed mounting clips thus, giving the customer 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 2.5kV terminals to base isolation.

In addition, the XPT IGBTs have a positive forward voltage coefficient, which enables parallel operation, thus facilitating scaling up the current capability with the use of multi module systems.

The XPT IGBT and Sonic diode combination in the 'Mini' modules are available in Converter Brake Inverter module (CBI) and six-pack topologies. The diode bridge input rectifier with break chopper supplement the 3-phase inverter six-pack stage in the CBI configuration. The MIXA20WB1200TMH is an example of a CBI module in the MiniPack2 housing containing the XPT IGBT and the Sonic diode. Also customized configurations are possible on request.
