Three Stability Assessment Methods Every Engineer Should Know About

Posted on 09 July 2014

      Many engineers are familiar with the Bode plot as an effective stability assessment method. However, some authors suggest and even teach that the Bode plot is the only method needed. This article shows why this thinking is short-sighted. A single, low cost instrument that can produce Bode plots, as well as two [...]

Sensor Module Ensures Optimum Battery Utilisation in Heavy-Duty Vehicles, called omniMoves

Posted on 08 July 2014

      Precise battery diagnostics makes maneuvering large, heavy-duty loads easier Isabellenhütte’s shunt-based IVT Modular sensor module measures the basic battery components’ current and voltage with an error rate of less than 0.1 per cent. This exceptional degree of accuracy provides for consistent power control and efficient utilisation, especially for high-capacity battery systems. This [...]

Efficient Microcontroller Peripheral Modeling with PLECS

Posted on 01 July 2014

      Microcontrollers play an integral part in controlling modern power electronic systems. Often, for system level simulations, the peripheral modules are simplified to improve overall simulation efficiency. In this study, efficient modeling of high fidelity peripheral models is discussed and the advantages of simulating power electronic systems with these models have been investigated [...]

Precise Evaluation of Input, Output, and Reverse Transfer Capacitances of Power Devices

Posted on 30 June 2014

      Increasing importance of capacitance measurement The switching frequency in power conversion circuits is increasing. This is primarily to reduce the size of passive components such as smoothing capacitors and reactors. Accurate characterization of device parameters affecting switching performance become more important as higher switching frequencies increase power circuit switching losses. By Hisao [...]

7th Developer Forum on Rechargeable Battery

Posted on 16 June 2014

      For three days the tiny city Aschaffenburg was the capital of the battery world. In recent years, the rechargeable battery developer forum with trade show organised by has developed into one of the most important European sector meetings for all rechargeable battery manufacturers and their suppliers and customers. By Marisa Robles [...]

Posted on 13 June 2014

      Smart-grid and Electric hybrid-vehicle devices tests and validation made easy with the power of FPGAs This article presents a versatile test gig for controlled systems and devices such as electric hybrid vehicles (HEV) and smart grid controllers. At the core of this Hardware-In-the- Loop (HIL) test systems are a set of FPGA-based [...]

Efficient 3D Modeling Tool for Computation of Inductive Coupling Effects

Posted on 11 June 2014

      Nowadays 3D modeling to compute electromagnetic fields is widely disseminated. It is used to evaluate electrical properties of components, assemblies and whole systems. In most cases it is a very time consuming process. Scientists of the Fraunhofer IZM developed a new tool for magnetic coupling computation with an effort reduction of 80% [...]

eScooter is Gaining Speed

Posted on 10 June 2014

      The life of Swiss postmen in some rural areas may just become a bit easier: In a pilot project they will be equipped with eScooters. Complex power electronics is required to drive the electrically powered two-wheelers and intelligent thermal management ensures reliable operation. This is where HSMtec enters the picture.

Easy Conversion

Posted on 09 June 2014

      A look at how to implement an analogue-to-digital conversion in a low bandwidth application By Mark Pallones, Kristine Angelica Sumague and Mike Gomez, Microchip Implementing an analogue-to-digital conversion in a circuit is one of the most common tasks facing designers and one that can be done in various ways. But for many [...]

MaxFlux – Magnetically Biased Inductor

Posted on 05 June 2014

      Utilising the core to its fullest! In modern topologies the inductive components require most of the space and contribute significantly to the total weight and system costs. Therefore the biggest potential for achieving a compact and cost efficient system lies in the optimization of these devices. Most of the effort made in [...]
