N2 - This paper describes the parallel connection of 4.5kV Integrated Gate Commutated Thyristors (IGCTs) and diodes. The impact of varying device characteristics on the stationary current distribution of parallel connected semiconductors is investigated. Possible solutions to improve the current sharing at steady state are presented. A thermal stabilization effect of parallel connected IGCTs is discussed. Furthermore, the behaviour of parallel connected devices during switching transients is investigated experimentally in a 1.5kV, 5kA buck converter. Especially the impact of asymmetrical circuit layouts, different turn-on and turn-off delays and junction temperatures are considered. It is shown, that a substantial current derating is necessary to enable a reliable operation of parallel IGCTs and diodes.
