Abstract :
The characteristics of three GTO structures with conventional, short and transparent anode, that is, GTO, SAGTO and TAGTO, are analyzed by using MEDICI simulator. The characteristics of TAGTO are illustrated by comparing with GTO and SAGTO. The results show that the transparent anode with an additional n-layer buffer used in TAGTO devices can further improve its blocking and switching characteristics simultaneity, and hardly effect on its conducting characteristics. Lastly, the mechanism of the transparent anode is revealed by analyzing the switching characteristic of the TAGTO
