Texas Instruments has expanded its TMS320C2000 microcontroller (MCU) digital power family to help engineers jump start digital-power design. Digital-power designs rely upon a microcontroller that runs power-control algorithms in the digital domain while it controls power in the analog realm. For complete information, visit: www.ti.com/digpwr-pfc-pr-sw.The company grouped its announcement into three sections:1. More than 25 free, modular digital-power software blocks are now available in the controlSUITE software. The free, open-source, and modular digital-power libraries let developers change control techniques in software, so they need not modify or redesign power-related hardware. TI has optimized the software blocks for both the Piccolo C28x core and the control-law accelerator (CLA). For information on the CLA, visit: focus.ti.com/lit/ml/sprb197/sprb197.pdf.2. The new High Voltage PFC Developer’s Kit provides hardware and software needed to quickly implement digital power-factor correction (PFC). The Piccolo F28027 kit (Part no: TMDSHVPFCKIT, $US 249) includes hardware and software for two-phase 300-W interleaved power-factor correction and TI claims engineers can get up and running in under 10 minutes. An isolated JTAG port lets engineers test and debug code without exposing their lab PCs to high voltages.3. Biricha Digital Power Ltd. now offers training that gives engineers a solid foundation in digital-power theory and extensive hands-on lab exercises. The 3-day workshop provides an introduction to digital-power technology, a step-by-step design of a digital power supply (buck topology), and explanations of how to use the Piccolo MCU in digital-power designs. For course information, visit: www.biricha.com/. The 3-day course costs $US 1995.Have you used digital control of power-supply or PFC circuits? –Jon Titus
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
