       with Eric Lidow, Chairman of the Board and founder of International Rectifier By Bodo Arlt, Editor BPS   Bodo Arlt: What are your feelings about today’s business culture? Eric Lidow: Today, due to the existence of the Internet, most businesses start operating internationally and are able to call themselves international. We are [...]

The HiPak IGBT Modules

Posted on 01 July 2007

      Packaging Technology for Reliable Operation A family of HiPak modules based on ABB’s own SPT and SPT+ IGBT and diode chips have been developed for the Traction and Industrial Markets. In this article, we will focus on the development of the packaging technology and show how the modules are designed for long [...]

High Performance Insulated Gate Bipolar Transistors

Posted on 01 July 2007

       Advanced technologies including relevant novel process and design concepts. Among many power semiconductor devices, IGBT has been attracted a considerable attention as a key semiconductor component for power industry due to huge potential to cover large areas of applications. To achieve higher performance and lower cost of IGBTs, extensive research and development [...]

Digital Power-Conversion for the Analogue Engineer

Posted on 01 July 2007

       MOSFET replaces the rectifier in the circuit It is no secret that, in the past, analogue engineers have struggled with the complexity of designing power supplies that require multiple outputs, coordinated load sharing, hot-swap capability, or extensive fault handling. By Bryan Kris, Staff Architect, Architecture & Applications, Digital Signal Controller Division, Microchip [...]

Line Voltage Rated PPTC Devices

Posted on 01 July 2007

       Protection for appliance motors and transformers The popular PPTC (polymeric positive temperature coefficient) resettable circuit protection device is now available in line voltage ratings and offers a simple, cost-effective alternative to fuses and bimetal protectors used in home and professional-grade appliance motors. By Faraz Hasan, Global Industrial and Appliance Marketing Manager, Raychem Circuit [...]

Encapsulated 6A to 12A DC/DC μModule Regulators

Posted on 01 July 2007

      Mounting like an IC and include the inductor, MOSFETs and Capacitors A major obstacle in improving the performance of point-of-load (POL) regulators has been in reduction of their size while increasing output power capability. This is in response to the popularity of densely populated PCBs in high-power applications such as embedded systems [...]

Magnetics Update –Taking Care of Noise in Power Designs

Posted on 01 July 2007

       Right-First-Time Design with RoHS-Compliant Inductors Magnetic component technology cannot advance in line with Moore’s Law, but designers are under pressure to meet tough targets for miniaturisation, time to market and cost. A wide choice of inductors, as well as concise component selection guidance, are both necessary to deliver advanced products on time [...]

A New Class in Power Electronics Simulator

Posted on 01 July 2007

      The simulator is updated on a regular basis The demands on power electronics hardware designers are getting higher and higher. In the past, it was common practice that new developments were funded based on design targets only, knowing that new features will justify almost any price. This has changed dramatically over the [...]

Snapshots of Product Innovation at PCIM Nuremberg

Posted on 01 July 2007

      Generation of IGCTs with Increased turn-off Current ABB launches a new generation of high power Integrated Gate- Commutated Thyristors with substantially increased turn-off capability. The new generation, designated “High Power Technology”, is capable of switching nearly 50% more current than the current series while still fitting within the same mechanical dimensions of [...]
