Infineon Technologies AG announced two new power module platforms designed to improve the performance of high-voltage IGBTs in voltage classes from 1200V up to 6.5kV. To make the benefits of the new module broadly available, Infineon is offering a royalty-free license of the design to all providers of IGBT power modules. First products using the platform concept will include the high voltage classes 3.3kV (450A), 4.5kV (400A), and 6.5kV (275 A) with a newly designed package measuring 100mm x 140mm x 40mm. The new modules will be introduced during PCIM 2015. Additionally, a package design for the lower voltage classes is being developed.
Reliable, high performance IGBT modules are a workhorse technology for electrical switching of industrial and traction drives, wind and solar energy systems and long-distance electrical transmission. Through a more than twenty-year history of use, chip technology developments have allowed IGBTs to meet demands for higher energy efficiency and higher operating temperature, as well as miniaturization, reliability and cost reduction with little modification to the standard packaging technology. As applications face more and more demanding and harsh environments this approach is reaching its limit, making a change in package technology of high-power modules a key to continued performance improvement. The new module platform addresses the emerging system requirements for high-power density, energy efficiency, long lifecycle and robustness. Its flexible concept allows the connection of similar parts in parallel, thus enabling a simplified structure to be used for the DC link terminal and capacitor. The AC terminals can be connected in parallel with only one busbar. The flexibility and scalability of the new modules will simplify system design considerably, thus supporting the time-to market requirements of developers. Utilizing the latest package technology the new high-power module also will help to reduce overall system cost and ensure future-proofing of designs.
