Silicon Carbide (SiC) 10KW Interleaved Boost Converter Achieves 99.1% Peak Efficiency

Posted on 04 December 2012

      SiC can help maximize performance while maintaining and even lowering overall system cost This article demonstrates a 10KW interleaved DC/DC boost converter with next generation 1200V silicon carbide (SiC) MOSFETs and Schottky diodes. The converter design proves the advantage of using SiC power devices with high frequency operation compared to conventional silicon [...]

Thermal Interface, A Key Factor in Improving Lifetime in Power Electronics

Posted on 04 December 2012

      Dedicated materials can dramatically improve the thermal situation In the majority of applications, the thermal interface dominates the thermal transfer with massive influence on the lifetime By Dr.-Ing. Martin Schulz, Infineon Technologies Increased demand in lifetime is an ongoing trend especially in applications like e-mobility or renewable energies. Likewise, the demand in [...]

    CeraLink offers many benefits for DC link circuits of inverters for e-mobility. The CeraLink™ capacitors offers many benefits for stabilizing and filtering the DC link circuits of power inverters – particularly in comparison with conventional capacitor technologies. Developers of topologies with new fast-switching IGBT modules will profit from this innovation. By Dr. Günter [...]

EN50155 Compliance to Railway Standards

Posted on 04 December 2012

      The whole process requires dedication and commitment “Ich verstehe nur Bahnhof” is a common German phase which translates literally into “I understand only train station”, but has the same meaning as “it’s all Greek to me!” I must admit, it was the first thought that popped into my head when I started [...]

Medium-Voltage High-Speed Switches with IGBT Power Semiconductors

Posted on 04 December 2012

      Solid-state semiconductor circuit-breakers have been used successfully for years in low voltage applications in the form of solid-state relays or, in the higher power range, using larger discrete power semiconductors. Since they work without any mechanical switching contacts, there is no mechanical wear and no need for any maintenance with this type [...]

CoolSiC™ JFET Driver for Direct Drive Topology

Posted on 02 November 2012

      SiC switches show best performance in conduction and switching losses Last year the CoolSiCTM JFET with its low power losses, high reliability, and robustness had been in-troduced. Now the first dedicated galvanically isolated unipolar JFET gate driver is presented. The driver is optimized for the Infineon normally-on SiC JFET family utilizing the [...]

Motor Control in Mind

Posted on 02 November 2012

      Completing the toolchain for fast, efficient Motor-Drive Design Field-Oriented Control has become the preferred option for many of the motor drives used in industrial and consumer applications. However, despite an abundance of suitable IP being available to developers, delivering true solutions requires a high degree of support - including intuitive tools to [...]
