The IGCT has potential advantages in terms of efficiency, reliability, and cost for MMC applications. However, the large anode reactor, complex low potential power supply scheme, and high driving power limit the application of IGCTs in power electronics systems.
IGCT converter is very low. The converter power can be increased by using larger IGCT modules, larger reactors and capacitors. The benefit being that the overall number of converter components and its FIT rates remains at the same low level. Outlook into new IGCT products Development programs within ABB are on-going to further improve the ...
IGCT technology employs conventional pressure contacts, but adopts a new approach. Drive unit, power semicon-ductors and cooler are integrated in a single functional unit and optimised wafers in standard housings have taken the place of the array of chips in expensive parallel configurations. Engineering and manufacture take less time and

The IGCT''s turn-on/off control unit is an integral element of the component. It only requires an external power supply and its control functions are conveniently accessed through optical fiber connections. The device''s control power consumption typically ranges from 10 - 100 W. The IGCT is optimized for low conduction losses.

Due to its on-state operation in thyris-tor mode, the IGCT has inherently lower conduction losses than a comparable IGBT device. The buffer layer, which can be used with the IGCT as well as with the IGBT, is the common denominator that causes these two devices ...
