Comparison between HiPerFET™ MOSFETs and Super Junction MOSFETs

Posted on 27 May 2013

      With the introduction of P3-series HiPerFET™ power MOSFETs, IXYS sets a milestone in HiPerFET™ technology, provides one of the best solutions in power MOSFETs for medium to high frequency designs. These devices have an optimum combination of low on-resistance (RDS(on)), low gate charge (QG), a fast intrinsic diode for low reverse-recovery (Qrr) [...]

EMC for Renewable Energy

Posted on 27 May 2013

      The use of renewable energy is growing worldwide. Higher numbers of ever more complex systems and installations are leading to a growing need for EMC solutions – especially for new high-power converters. EPCOS components ensure that wind power plants do not introduce interference into the grid. By Ronald Seeger, TDK The rotors, [...]

Driver and LED Companies must Work Together to Achieve High-Efficiency, Practical LED Lighting

Posted on 27 May 2013

      The story of a PAR 38 LED spotlight design Delivering real-world LED lighting systems that live up to their billing – reduced power consumption, increased life, improved efficiency – has not proved to be a simple task. Of course, LED lighting is being increasingly used in many applications, but there have been [...]

Synchronization of SMPS Power Modules

Posted on 27 May 2013

      A Practical Application for Cyclone V FPGA Power Requirements The integration of multiple power modules on a single power board allows for specific load requirements to be achieved. This arrangement, commonly known as Distributed Power Architecture (DPA), matches each individual DC/DC converter to a specific load, resulting in an improved dynamic response [...]

The Good Gap-Filling Guide

Posted on 27 May 2013

      Proper thermal management in equipment such as consumer electronics, handhelds, automotive modules and power supplies requires engineers to eliminate air gaps between hot components and nearby heat-dissipating surfaces. Understanding how to select and use the wide range of gap fillers now on the market is a valuable skill. By Riaz Ahmed, Chomerics [...]

Capacitors Built to Customer Specifications

Posted on 27 May 2013

      Historically, capacitor designs have been primarily defined by the final cost of the capacitor itself. Fischer & Tausche Capacitors (FTCap) suggests a more comprehensive approach because cost is not just limited to the purchasing price of the capacitor. By Peter Fischer, Fischer & Tausche Customers cannot ignore installation, test, and maintenance costs. [...]

Advanced Regulator Modules Bring Flexibility to High-Density Power Subsystems

Posted on 27 May 2013

      The long-standing trend of increasing efficiency in power-conversion, from the upper 80s of percent to the mid and upper 90s, has come thanks to innovations spanning power-switching device designs, converter-control techniques, and component-packaging technologies. Beyond the obvious operational cost benefits that high-efficiency power subsystems bring to the products they inhabit, one consequence [...]

Improving Efficiency on AC-DC Supply Efficiency

Posted on 27 May 2013

      Can further gains continue to be made? It's tough to get improve efficiency when supplies are already at 90%, but it can be done by focusing on passive and active components, digital control, supply topologies and packaging By Don Knowles, VP Engineering, N2Power For AC-DC power supply users, the good news is [...]
