Christian André: The renewable energy and Electric drives in Automotive are great opportunities for the companies in power semiconductor. ROHM Semiconductor is a new comer [...]

A Power Module Concept for the Low Voltage MW Class

Posted on 02 September 2013

      Various applications like renewable energy generation and high power drives in the MW range have an increasing demand for high reliable power module concepts addressing the operation in a harsh environment. Next generation designs e.g. of wind turbine inverters need to be more reliable, more compact and less expensive to bring down [...]

Test and Validation of Grid Connected Battery Storage Controller

Posted on 02 September 2013

      Desktop power electronics control testing Transmission and distribution (T&D) grid connected energy storage controlled by power electronics (PE) improves power quality, and reduces the need for additional investments in T&D infrastructure, but assumes well tested control algorithms that comply with T&D grid codes. To streamline the process of grid connected converter controller [...]

Soft Switching Three Level Inverter (S3L Inverter)

Posted on 02 September 2013

      New circuit topology for high-power PWM inverters with integrated du/dt filter and high efficiency The S3L inverter is a novel circuit topology for three-level PWM inverters in the medium and high power ranges. Soft switching is used for all commutations, which therefore have no switching losses on principle. The result is significantly [...]

Are SiC Solutions Really Still More Expensive than Si Solutions Today?

Posted on 02 September 2013

      Reduction of the overall system costs by means of CREE's 2nd generation SiC-MOSFET generation The following article intends to refute the common statement that SiC power components are much more efficient than Si components, but are still too expensive. By Christopher Rocneanu, Field Application Engineer, MEV Elektronik Service GmbH For more than [...]

Construction and Agricultural Machinery as Hybrids

Posted on 02 September 2013

      Although construction, agricultural and forest machinery is still dominated by Diesel and hydraulic drives hybridization fairly suggests itself. If the frequently occurring load peaks are buffered electronically cost, consumption as well as the emission of exhaust and noise are reduced considerably. By Tomi Ristimäki, Marketing, VISDEDO and Kurt Bertleff, Marketing, WIMA Diesel [...]

What's So Super About Nickel Supercapacitors?

Posted on 02 September 2013

      The growing emphasis on environment-friendliness, energy-saving and general operational efficiency means there is a greater role in the transport industry for energy storage systems of all kinds. One relatively new form of energy storage – the nickel carbon supercapacitor – is finding favour in a wide variety of applications, especially where high [...]

A System Approach, Comprehensive Motor Solution

Posted on 02 September 2013

      Re-Build Your PMSM/BLDC Designs and Provides Faster Design Time The irreversible trend of moving to high efficiency energy design for motor has been well known and recognized. From high power fan in industry to middle power fan in major home appliance such as range hood fan, or further down to small power [...]

Precise Characterization of Power Semiconductor Devices Made Affordable

Posted on 02 September 2013

      Power semiconductor devices are core components of power electronic systems. Knowing their characteristics well helps reducing costs and increasing reliability. When designing a system, it is important to consider the spread of parameters of the various components. But when it comes to the verification of the design, how can we know about [...]
