Keep Cool

Posted on 29 June 2012

      Liquid Cooling Meets Advanced Requirements of Power Electronics So far nobody has succeeded in designing an electronic component with a 100% efficiency, so power that is lost during operation is transformed into heat. In order to avoid exceeding the acceptable temperature limit and subsequent destruction of the component, this heat needs to [...]

First Principle Optimization of Power Module Baseplate

Posted on 29 June 2012

      Simulation results are found in good agreement with data out of experiments One of the primary concerns in the design of power modules is the base plate shape. It plays a vital role in the thermal and mechanical stability of the complete module. This paper deals with the generic optimization scheme for [...]

IGBTs in Reverse Gear

Posted on 29 June 2012

      The complex interplay of freewheeling diodes and IGBTs State-of-the-art power semiconductors are intended to switch quickly in order to reduce dynamic losses. Once an IGBT turns off, the load current commutates to the freewheeling diode. To avoid undesirable side-effects , these two semiconductors have be very well matched in terms of their [...]

Energy Harvesting Systems Power the Powerless

Posted on 29 June 2012

      Energy harvesting solutions allow electronics to operate where there is no conventional power source and without the need to run wires or make frequent visits to replace batteries. This article provides an overview of energy harvesting applications and their benefits, how they work, and the challenges that designers must address to implement [...]

Posted on 29 June 2012

        Power Solutions for Data Centre and Cloud Computing Applications Move Closer to Production  High efficiency cabinet or rack-level architecture power solutions are necessary to improve the overall power efficiency of systems that perform the increasing number of data centre and cloud computing applications. Power architectures such as IDT’s cool- RAC include [...]

One More Way to increase the Recovery Softness of Fast High-Voltage Diodes

Posted on 29 June 2012

      By Chernikov A. A., Gubarev V. N., Stavtsev A. V., Surma A. M., and Vetrov I. Y., Proton, Electrotex ISC   Due to the development of the power converters based on the highvoltage IGBT and IGCT the demand for the high-voltage fast recovery diodes (FRD). The requirements to the high-voltage FRD of [...]

1mW Isolated DC/DC Converter

Posted on 29 June 2012

      Extreme low current consumption of the microcontroller Nowadays we’re living in an era of metering and sensing. More physical factors are measured and collected then ever before, data is linked up and by the use of the internet sensor data can be looked up from every place of the world. The tendency [...]
