| Abstract |
The IGCT technology (Integrated Gate-Commutated-Thyristor), which is based on the concept of the hard driven GTO, reduces inherently the storage time of the turn-off device to 1 us and allows the robust series connection of high power turn-off devices. The homogenous operation, especially during turn-off, allows the reduction or even elimination of the dv/dt snubber. Together with an improved device design (buffer layer, transparent anode) the inverter losses and costs are dramatically reduced. The first application of this technology in a 100 MVA intertie based on the 1st generation of series connected IGCTs is discussed and operational experience is presented. |
