ISOPLUS-DIL™ Series Designed for Highest Reliability

Posted on 17 July 2012

      The GWM series in ISOPLUS-DIL™ package (Dual-In-Line) has been developed to production standard. It is a transfer moulded module which combines the advantage of a robust package (like discretes) with the functionality of a module with isolation from heat sink and complexity in the circuit. The GMM series is an improved version [...]

Extending the OptiMOS™ 3 Power MOSFET Family

Posted on 17 July 2012

      Performance for an energy-efficient world Today, developments within the power conversion sector are driven by customer requirements for energy saving and physically smaller designs. Continual development of converter topologies for AC/DC and DC/DC has resulted in improved efficiency at converter level. Power MOSFETs are the core component of power converters in this [...]

How Low Can You Go?

      New applications thanks to lower leakage current The SIFI series of 2-line filters has proved itself in numerous applications over many years. The new SIFI® generation with reduced leakage current is now also suitable for medical engineering applications. By Volker Scharrer, EPCOS   Increasing numbers of electronic appliances and their interaction mean [...]

Now We are Cooking

Posted on 17 July 2012

      A new approach to induction heating design Looking at a new ‘multizone’ design that allows efficient heating while reducing the number and power rating of converters and eliminating the need for relays or solid state switches. The demand for induction hobs - in which electromagnetic coupling between a ferromagnetic saucepan and concentrated [...]

Mixed Signal and Power Integration Packaging Solutions

Posted on 17 July 2012

      Multiple-die packaging techniques for very mixed silicon processing requirements Even before the first transistor was invented, there has been a constant drive to integrate more and more functionality into a single product. There are the obvious cost benefits to put more functions into the same package or die area, but there are [...]

The Correct Power Supply

Posted on 17 July 2012

      The choice has become easier To find a suitable power supply for your own application: developers and project engineers can tell many a tale about this. Despite the fact that there is an enormous choice on the market, the one that fits the bill exactly is never amongst them. Compromises regarding dimensions, [...]

A Modular Approach for Production

Posted on 17 July 2012

      High speed testing of power semiconductors With an experience that started in the early 1960's, LEMSYS developed in the beginning of the 1990's a modular approach of power semiconductors commencing with the test of dynamic parameters. The main concern of this development was the possibility to build in a relatively short time [...]

Thermal Analysis of Semiconductors

Posted on 17 July 2012

      Thermal simulation predicts the junction temperature and life time of semiconductors The design of power converter includes necessarily the calculation of power loss and temperature rise in the semiconductors and heat sink. This article shows the procedure of evaluation junction temperature and life time of semiconductors. By Tobias Hofer, Negal Engineering GmbH [...]

Design in Extreme Environments

Posted on 17 July 2012

      Fit more watts into the same or less amount of space Nothing works without power – this also applies to electronic devices and, ultimately, the connectors within. There we take a look at the recent developments in power connector design to address the ever increasing needs of high-end server and storage applications [...]
