The Optimal IGBT for Motor Drives Applications

Posted on 01 May 2008

      Drive with the XPT IGBT IXYS introduces the XPT IGBT, the newest generation of short-circuit rated IGBTs with paralleling capabilities and competitive performance. Implementation of innovative cell designs and new process technologies resulted in improved IGBT characteristics. Combination of the XPT IGBT with the recently introduced SONIC diode delivers fast and soft [...]

Driver Core goes Fully Digital

Posted on 01 May 2008

      Power electronic systems in the voltage range of 1200V and higher call for fully insulated signal transmission for both PWM and IGBT status signals. In order to achieve sophisticated and repetitive signal transmission for all signals, including sensing signals, a fully digital driver core solution was developed to drive and control IGBT [...]

Accurate Dynamic Power Measurement

Posted on 01 May 2008

      Achieving Efficiency, Reliability and Cost Advantages By Richard Kroeger, Applications Engineer, International Rectifier, Durham, NC   Designers of modern systems are using active power management techniques to limit energy consumption and maintain equipment within a tight thermal envelope for cost and size savings. However, established techniques for dynamic power monitoring can be [...]

Current Limiting for Redundant Power Systems

Posted on 01 May 2008

      A New Approach using Multiswap The new TPS2359 hot-plug controller integrates all of the power management functions for two AdvancedMC™ (AMC) modules. Its current limiting circuitry enables designers to meet tight AMC requirements. This is relevant because many applications use redundant supplies. A unique feature called multiswap maintains a fixed current limit, [...]

IGBT Behavior under Short Circuit and Fault Protection

Posted on 01 May 2008

      Using Two-Step-Soft-Turn-Off Gate Driver In inverter driven UPS or motor applications, the IGBT can be destroyed when it is turned-on into a faulted motor or an output short circuit or an input bus voltage shoot through. Under these conditions current through the IGBT increases rapidly until it saturates. After fault detection, depending [...]

Optimizing Thermal Solutions

Posted on 01 May 2008

      Software cuts design costs CFD (computational fluid dynamics) thermal analysis software is freeing engineers to create smaller, more reliable boards and systems, while simultaneously reducing development time and costs. The software solves the differential equations that model airflow and heat transfer and presents the results as 3-D color-coded simulations that accurately show [...]

The Tailor Made Thermal Solution Kit

Posted on 01 May 2008

      GraviTherm is a kit designed to transport heat away Electronic controls and computers become more and more important to all sectors of our life. Today there are almost no industrial applications which work without electronic components to control and to monitor the processes. The use of these components makes production processes, administration [...]

Advantages of SiC Schottky Diodes

Posted on 01 May 2008

      Fast switching are the targeted power electronics solutions SiC is discussed as a future high performance replacement of the silicon power components. The new technology enables products with almost ideal behaviour. Currently, SiC Schottky rectifiers are already available as qualified standard products By Ernö Temesi, Development Engineer, Vincotech Hungary Ltd.   This [...]

Taking Transducer Technology to the Limits of Current Measurement Accuracy

Posted on 01 May 2008

      HPCT transducer for the future of MRI scanning The development of magnetic resonance imaging (MRI) has led to an increased ability to diagnose and, subsequently, treat a growing number of physical conditions at the cellular level, perhaps most notably cancer. As a diagnostic methodology, MRI continues to evolve but for some time [...]

Powering The Next Generation of Digital Television

Posted on 01 May 2008

      The power density of a switch plays a big role Television’s evolution from analog to digital alters the very concept of what a television is. While the main function of a television remains as a method for watching broadcast channels, it has also evolved, becoming a multimedia center in itself. By Mike [...]
