Interview about Power Supply Technology with Matt McKenzie, President of CUI Inc

Posted on 17 July 2019

      By Bodo Arlt, Editor BPS   Bodo Arlt: How did CUI start and what was the vision? Matt McKenzie: CUI was started by my father, Jim McKenzie, in 1989. It was originally started as a joint venture with a Japanese firm called Stack Electronics. Stack is a manufacturer of high end probes [...]

Low-Cost Highly Integrated Gate Driver Core

Posted on 10 July 2019

    SCALE-2 Simplifies Custom-Specific Solutions The highly integrated SCALE-2 chipset allows the time-to-market, development effort and production cost of custom-specific IGBT gate drivers to be dramatically reduced. As an example, the new 2SD300C17 is presented that is compatible with the 2ED300C17 from Infineon in mechanical, functional and parametric terms. The chipset has been developed [...]

      Mechanical design of a converter will become much easier The PrimePACK™ housing could become the new cost-effective standard for 2 in1-packages, which provides many mechanical, thermal and electrical advantages. By Peter Dietrich and Thomas Heinzel, Fuji Electric Europe GmbH and Dr. Masahito Otsuki, Fuji Electric Systems Co. Ltd.   Until now high [...]

On the Pulse of Power Electronics

Posted on 10 July 2019

      The desaturation behaviour of the IGBT allows to turn them off by the IGBT driver Just about 30 years ago, fast thyristors, RCTs, GATTs as well as GTO and BJT were the best components available at the time for power electronics. Each 100V reverse voltage upwards was keenly fought over, each microsecond [...]

Wide Input, Low Output POL Regulators

Posted on 10 July 2019

      Delivery of Benchmark Efficiency With High Density Capable of handling input voltages as wide as 1.5V to 16V, the second generation integrated point-of-load (POL) regulators are designed to deliver output voltages from 0.7V to 12V at peak efficiency greater than 96%. Thanks to programmable switching frequencies up to 1.5 MHz, this voltage [...]

A New Generation of Lower Power Consumption Power ICs

Posted on 10 July 2019

      Reducing switching frequency at no load for lower power consumption Today's environmental concerns are more complex, far-reaching and interconnected than in the past, and using energy more efficiently has become a global mandate. In recent years, consumer power supplies are encouraged to abide by energy-saving specifications, such as California Energy Commission (CEC) [...]

Engineering publications are loaded with market analysts’ comments on the potential of digital power and announcements regarding new digital power products from leading IC companies. These serve to [...]

Power Modules in High-End Market Segments

Posted on 10 July 2019

      A low output ripple is mandatory as well when supplying analogue systems The new SIMPLE SWITCHER® Power Modules from National Semiconductor reach the highest possible level of “Ease of Use” by integrating an inductor and a monolithic synchronous regulator within one power package. Professional power designers have far more requirements than “Ease [...]

Wideband High Temperature Optocoupler

Posted on 10 July 2019

      Serving isolated AC/DC and DC/DC converters in HEV and PHEV Isolated AC/DC and DC/DC converters for onboard charger and power supply in HEV and PHEV require careful examination of popular phototransistor optocouplers as error amplifier feedback. Various performance challenges surface to meet high temperature environment up to 125°C, long operating life time [...]

Electrolytic Capacitor Lifetime Estimation

Posted on 10 July 2019

      Key parameters are necessary to predict lifetime Aluminum Electrolytic Capacitors (“elcaps”) are essential for the function of many electronic devices. Frequently, the lifetime of these devices is directly linked to the lifetime of the elcaps [9]. By Dr. Arne Albertsen, JIANGHAI EUROPE GmbH   This article reviews the construction of elcaps and [...]
