ABB Asymmetric Gate Turn-off Thyristors (GTO)

Asymmetric GTOs are divided in two categories: Buffer layer and Standard. Buffer layer GTOs have exceptionally low on-state and dynamic losses. Fine pattern types (5SGF) are optimized for fast switching and transparent emitter (5SGT) for low on-state losses. The Standard GTOs have excellent trade-off between on-state and switching losses.

Mitsubishi Launches LV100-type IGBT Module

Mitsubishi Electric Corporation announced the launch of its LV100-type T-series insulated-gate bipolar transistor (IGBT) module for industrial uses. The LV100 package, which achieves high versatility and high current density, has been used widely in railway and electric power applications and now has been adapted for industrial uses. It is expected to help reduce the size and power loss of power converters, specifically inverters used for renewable energy applications such as photovoltaic and wind-power generation, and also high-capacity motor drives.

ABB 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.
