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 [...]

Stacks Selection and Calculation using Web-based IPOSIM Tool

Posted on 02 November 2012

      Selection, loss and thermal evaluation of Infineon’s IGBT stacks The web-based IPOSIM has been established as a powerful simulation tool for design engineers when analyzing power electronic components arranged in standard topologies. The latest IPOSIM version has extended its capability to simulate a complete IGBT stack with three-phase 2-level topology By Adalberto [...]

Smart Charging on the Go

Posted on 02 November 2012

      Charge any device that complies with WPC specifications Smartphones provide communications and access to the Internet everywhere. Now, wireless charging promises to let mobile devices do away completely with cords. TDK has developed ultra-flat power transmission coils that meet the most demanding Qi specifications Wireless Power Consortium (WPC). Based on material of [...]

Using de-rated DC Multilayer Chip Capacitors for AC Applications

Posted on 02 November 2012

      You are hungry to know more about their expected behaviour Engineers have been using de-rated DC multilayer chip capacitors (MLCCs) for years to meet the need for capacitance in AC circuits higher than the 4.7nF norm. While such a solution provides the required reliability, that is, the device will work in the [...]

Innovative Development of Modular Switch Mode Power Supplies

Posted on 02 November 2012

      From the simple to the best Power supply modules have been well-known from the mid–‘80s, when the technical concept and design of modular converters was first developed, and modular SMPS became basic elements in the design of devices and the electronic power systems (EPS) used in many applications – from commercial to [...]

First Frequency Converter for Compact Drives in Railway Applications

Posted on 02 November 2012

      Introduced at InnoTrans 2012 The compact drive is certified following to the railway standard EN 50155. Railway applications require a much higher quality level and more robustness than other industrial designs, especially in terms of mechanical and temperature shock resistance. The drive with 3 kW is used to drive a fan for [...]

European Engineers: so close at hand

Posted on 31 October 2012

      By Dr. Walter Demmelhuber, SindoPower International Power Electronics Engineers are still hard to find in Germany. Why not look in the nearby countries of the EU and make it easier for the engineers to migrate? Only recently SindoPower – part of SEMIKRON-group – was in the prime-time national evening news Tagesschau where [...]
