Flyback design problems – I am developing an open loop flyback converter. The image below is the result observed at 70v (Dc) Input. The waveform is of the voltage across drain to the source. I have used the diode-zener snubber but there is still some ringing. Read more Why is the damping resistor in our Bootstrap high […]
Thermoelectric assembly offers low cost of ownership
Global technology leader Laird has developed a smaller, more efficient option to cool or heat vital electronics used in outdoor kiosks and enclosures including telecom, battery backup, industrial and other cabinets. The AA-230 Series air-to-air thermoelectric assembly (TEA) offers lower cost of ownership by maintaining the appropriate temperature range using less energy than standard air-to-air […]

U.S. plays catch-up with flexible electronics
by Leland Teschler, Executive Editor A big effort is underway in the U.S. to develop the kind of manufacturing expertise necessary to cheaply produce electronic circuits able to bend and flex. The idea of putting electronic circuits on pieces of plastic that can bend certainly has a lot of sex appeal. And no wonder. The […]
