Implementing Gate Drivers for 3-Level NPC-2 Power Modules with Reverse Blocking IGBTs

Posted on 27 October 2014

      Although 3 level converter topologies can lead to reduced total harmonic distortion and hence minimise the size and cost of filtering at the output stage, the best known configuration, NPC1 (Neutral Point Clamped), usually increases the number of switching devices (IGBTs and diodes) required, which adds to the complexity of the system. [...]

SCALE™-2 IGBT Gate Drivers Ease the Design of Optimized Renewable Inverter Systems

Posted on 28 January 2014

      The 2SP0325 IGBT gate driver – a member of the SCALE™-2 plug-and-play gate drivers from CONCEPT – allows New Mega Power Dual IGBT modules from Mitsubishi to be driven efficiently in solar and wind power applications. The driver facilitates compact and reliable power converter design thanks to its high level of integration [...]

Using Advanced Active Clamping to Facilitate Simple, Safe and Reliable IGBT Driving in Multi-Level Topologies

Posted on 07 October 2013

      The Advanced Active Clamping (AAC) functionality implemented in CONCEPT’s SCALE™-2 technology allows multi-level converter topology designs to be simply and safely driven. In the event of an IGBT short circuit, all IGBTs no longer have to be turned off in a dedicated sequence to avoid excessive IGBT collector-emitter voltages. Instead, the AAC [...]

Thermal Evaluation of High Voltage Half Bridge EiceDRIVER™ ICs with Integrated Bootstrap Diode

Posted on 27 May 2013

      Consumer electronic applications and home appliances strive continuously for higher efficiency of applications and smaller form factors. The new 2EDL EiceDRIVER(TM) Compact familiy supports this requirement by integrating many helpful functions such as the bootstrap function. By Wolfgang Frank, Infineon Technologies AG, Neubiberg, Germany This article discusses various parameters such as switching [...]
