Embedded Systems: Take a New Look at Ada

October 28, 2008 11:14 am | by Robert Dewar, President and CEO, AdaCore | Articles | Comments

The world of computer technology has two incompatible characteristics. First, many computer systems have long lives. Second, students and many engineers pay attention to only the latest technologies and they believe old technologies have died out. The "yesterday's-fashion” phenomenon has applied to the Ada programming language, too. If engineers have heard of Ada at all, they may assume it is an old US Department of Defense technology that disappeared long ago.

Cover Story- Power Factor Correction Goes Digital

October 28, 2008 10:41 am | by Vinaya Skanda, Senior Applications Engineer, Microchip Technology. | Articles | Comments

Most power-conversion applications require a DC source, which uses a rectifier that draws non-sinusoidal line currents. As a result, line-current harmonics have become a significant problem and they lead to overheating of transformers and inductive equipment, degradation of system voltages and increased stress on components. In addition, stringent limits imposed on harmonic currents by international groups make the need to improve power quality even more important. Power-factor correction (PFC) can help solve these problems.

Motion Controller Manages Four Axes

Should Energy Star exist?

October 28, 2008 7:20 am | by Jason Lomberg, Technical Editor | Articles | Comments

The recent Energy Star controversy must inevitably be discussed in a broader context. To sum up current events: on June 2nd, the EPA violated Energy Policy Act (EPACT) 2005 by releasing a “technical amendment” (version 4.2) to their Energy Star solid state lighting criteria without consulting “interested parties” (i.e. industry).
