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 [...]

IGCT - A Highly Efficient Device with Continuing Great Success in High Power Applications

Posted on 03 February 2016

      For reliable and efficient operation in high power applications, the Integrated Gate Turn-off Thyristor (IGCT) is the ideal device. The main advantage besides high reliability is the low device losses resulting in low system losses. In this article we compare IGCT and IGBT based 3-level converters with respect to device and system [...]

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 [...]

Advantages of the 1200 V SiC Schottky Diode with MPS Design

Posted on 22 December 2015

      Single- and three-phase inverters in solar, UPS or energy storage applications today demand for high efficiency, compact designs and extended reliability. Inverter implementation in these applications is limited by silicon devices’ high dynamic losses when operated at 1200 V. Alternative designs using 600 V/650 V devices can partially improve efficiency. However, they [...]

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 [...]

Low Loss High-Power Thyristors for Industrial Applications

Posted on 19 November 2015

      Though one of the oldest semiconductor devices ever, the thyristor maintains a significant market share. This is because of its attractive price-performance ratio mainly due to the lowest ON-state losses and the easiest processing from existing gated switches. ABB has developed a new range of thyristors offering very low ON-state voltage drop, [...]

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, [...]
