These devices are designed for full-switching power factor correction in motor drive applications in the 3-6kW power range. The FPDB20PH60 (600V/20A), FPDB30PH60 (600V/30A), and FPDB50PH60 (600V/50A) all integrate two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor into one package measuring 44 x 26.8 mm. They are half the size of other devices, and use 40 kHz-switching operation for less power loss, typically providing 99 percent power factor. They have under-voltage and over-current protection through integrated gate-driving IC, and offer an isolation voltage rating of 2,500 Vrms/min.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
