SiC MOSFETs Enable High Frequency in High Power Conversion Systems

Posted on 05 February 2016

      Enhancing the performance of traditional IGBT-module-based power assemblies with SiC modules In recent years, 1.2kV and 1.7kV silicon carbide (SiC) MOSFETs have become a real alternative for power converter designers who currently use IGBTs. To date, the majority of the SiC MOSFET design wins have occurred in power converters in the low [...]

PLECS Goes Real-Time

Posted on 01 February 2016

      Plexim is expanding its PLECS product line with real-time hardware to provide a complete and one-stop solution for modern power electronics development teams. By Beat Arnet and Felix Prausse, Plexim GmbH Introduction Designing power converters is a complex task requiring advanced tools and processes. Power converters are sophisticated systems composed of multiple [...]

Reading Between the Lines

Posted on 20 January 2016

      Using data sheets correctly when selecting resistors When selecting a resistor for your application, there is more to bear in mind than you might think. In order to make a preliminary choice using a product data sheet, developers need certain background information and have to calculate some dimensions themselves. An example shows [...]

Wireless Charging: Power without Boundaries Becomes Available to the Masses

Posted on 14 January 2016

      Wireless charging has been in the wilderness, hidden in a chasm until standardisation, strategic partnerships and technology integration recently gathered pace. The market is predicted to become worth billions of dollars in the next few years - yet it has been the domain of a few Tier-1 companies as the resources and [...]

Rethinking Power Analysis

Posted on 08 December 2015

      The quest for increased power efficiency permeates every level in the electronics industry, from individual semiconductor components over circuits and modules to entire devices and even complex systems. From a power analysis point of view, every part of this spectrum has different requirements and poses different challenges. To keep up with those [...]

How Proper Applications of Thermally Conductive Materials will Improve Motor Power Density

Posted on 30 July 2015

      Motor designers have battled heat in motor designs for years. Thermal losses in electric machines rob motion systems of power and degrade efficiency. Excess heat can reduce reliability of motors and shorten their lifetimes. Meanwhile, electrification in all transportation sectors is driving requirements for motors with ever-higher power densities. By Anita LaFond, [...]

Now the company extends its power product range with some industry firsts. By Wolfgang Patelay, Freelance Journalist, Bodo´s Power Systems According to Dave Priscak, Director, Power [...]

Switching Behavior of USCi’s SiC Cascodes

Posted on 15 June 2015

      The co-packaged cascode device, combining a Silicon low voltage FET with a trench vertical SiC normally-on JFET, was recently introduced by United Silicon Carbide. This device has several benefits, including the ability to use standard 10V or 12V gate drive, high Vth (4.5V), fast temperature independent switching, avalanche and short circuit-ratings and [...]

Wireless Power Transmission with High Efficiency and Wide Dynamic Range for Extensive Applications

Posted on 15 June 2015

      Wireless power transmission has been known for many years, with inductive near field proximity coupling being the most commonly used technology. By Markus Rehm, Ingenieurbuero Rehm, Villingen-Schwenningen, Germany The demand for wireless power supplies is huge: Mobile devices, charged without wire or contact, are robust, splash proof, reliable, simple to protect against [...]
