How to Deal with TRENCHSTOP™ 5 IGBT in Power Applications

Posted on 07 October 2013

      While the main market for power applications is still seen in the drives segment, other segments focusing on higher switching frequency ranges gained importance. UPS, Photovoltaic, and Welding Applications, to name a few, have grown significantly in size in recent years. By Fabio Brucchi, Infineon Technologies AG, Austria In order to respond [...]

Bringing Intelligence to Battery Management for Industrial Applications

Posted on 07 October 2013

      Lithium-Ion (Li-Ion) battery technology first emerged in the early 1990s as the preferred high-performance solution for portable computing applications. By the end of the 1990s, it had become the battery of choice for mobile phones as well. By Upal Sengupta, Staff Applications Engineer and Rajakrishnan Radjassamy, Business Development Manager, Battery Management Solutions, [...]

SiC MOSFET-Based Power Modules

Posted on 07 October 2013

      Utilizing split output topology for superior dynamic behavior The body diode reverse recovery charge of a SiC MOSFET is lower than that of an Si MOSFET, but still not as beneficial as with SiC Schottky diodes. As the switching performance demands for new wide band-gap components increases, so do the requirements for [...]

Multiphysics simulation for designing laminated busbars

Posted on 07 October 2013

      Improvement of IGBT characteristics switching at higher frequencies has been a decisive factor in the development of smaller, more efficient power electronics converters. Today, the lowest possible system inductance is paramount to push today's state-of-the-art converters to their peak performance. By Antoine Gerlaud, Mersen St Bonnet France, Tom Giuliano, Mersen Rochester USA [...]

Power Block Innovations Enhance Synchronous Buck Converters

Posted on 07 October 2013

      Dual MOSFETs in PQFN packages, containing optimized synchronous and control MOSFET devices, enable designers to enhance the efficiency and power density of synchronous buck converters. A new evolution of the dual PQFN package featuring a single-clip connection to both MOSFETs, called power block, introduces an innovative internal structure that further increases efficiency [...]

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 [...]
