      Energy savings for applications by enabling current control Today’s Power Electronics world is experiencing a trend towards a greater degree of integration with a lower components count. This orientation can be seen everywhere, not only for electronic components, but also for the other areas of power electronics, like heat sinks, magnetics and [...]

      Extended temperature range for modern converter design The PrimePACK™ family is a new power module concept that is specifically designed to be integrated in modern converter setups. The most important electrical improvements concern the modules stray inductance as well as its interface to the driver board and the connection to the load [...]

      Better trade-off between device electrical performance and ruggedness New depletion-stop trench IGBT technology combines low switching losses with the traditional IGBT advantage of low conduction loss for applications such as voltage domesticand industrial-motor drives in the 2-30 kHz range. By Vijay Bolloju, Chiu Ng, and Jie Zhang, International Rectifier   IGBTs have [...]

       Using the new VIPer12A and VIPer22A software To supply the large number of electronics components required for home appliances, different power supply topologies can be used. We focus our attention on small appliances such as washing machines and white goods using non isolated SMPS. By Giacomo Mercadante, STMicroelectronics   The worldwide home [...]

      Micro-structure heat exchanger should be optimally designed Recent technical advances are driving the commercial acceptance and use of liquid cooling systems for high heat flux processors in computers and workstations By Girish Upadhya, Ph.D., Director, Thermal Design & Applications Development Cooligy, Inc., Mountain View, CA   The thermal characteristics of high-powerdensity CPUs [...]

       New modulation enables high output power As integration and features add complexity and reduce battery lifetime, the need to add wireless connectivity to a product has also grown. Since the introduction of short range radios (SRD), a wide range of applications has added wireless connectivity creating increased demand for cheaper and more [...]
