Application of Gate Drivers for 3-Level NPC-2 Power Modules with Reverse Blocking IGBTs
PCIM Asia June 2014
3-level topologies are typically based on the classical neutral-point-clamped (NPC1) topology with four power switches (IGBT) per half-bridge and two additional clamping diodes. A variant of this topology is known as the NPC2 topology which uses two IGBTs per half-bridge and two IGBTs connected as a common collector configuration in the clamping path. This paper discusses these differences and provides proven solutions that enable standard gate drivers to be adapted for use in NPC2 topology designs with RB-IGBTs.

Advantages of Advanced Active Clamping
Power Electronics Europe Decembre 2009
Power semiconductor manufacturers are offering IGBT modules with ever greater power densities. The limit is represented by the maximum power loss that can be dissipated; optimization criteria are the packaging technology as well as the conduction and switching losses of the semiconductor chips. The high current density of the modules together with high switching speeds place increased demands on the driving circuits, both in normal switching operation and under overload conditions. Advanced Active Clamping switching technology offers a solution showing how modern high-power IGBTs can be better utilized.
