Press-pack IGBT and diode modules

StakPak is a family of high power insulated gate bipolar transistor (IGBT) press-packs and diodes in an advanced modular housing that guarantees uniform chip pressure in multiple-device stacks.

Although the most common package for IGBTs is the isolated module, for applications requiring series connection, press-packs are preferred because of the ease with which they can be connected electrically and mechanically in series and because of their inherent ability to conduct in the shorted state – an essential feature where redundancy is required. Since IGBTs feature multiple parallel chips, there is a challenge - with conventional press-packs - in assuring uniform pressure on all chips. ABB has solved this problem with a patented spring technology.

The StakPak, optimized for series connection, features a modular concept based on sub-modules fitted in a fiberglass reinforced frame, which allows a flexible realization of a range of products for different current ratings and IGBT/diode ratios.
