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 […]

High voltage input cascaded input converter – We have to do a non-isolated SMPS for vin=120v to 400v, and vout = 100v, pout=300w. There is a “known” way to do this involving two cascaded synchronous buck stages. Do you know more detail of this “known” method? Read more Designing a charge controller for hybrid system – I […]
3000 Watt Mini Generator Powered Light Tower Released
Larson Electronics announced the release of a mini light tower featuring three 1000 watt metal halide lamp heads, a 3,500VA generator for operation, and an adjustable tower built on a wheeled frame for portability. The WAL-ML-3XM-3G mini light tower from Larson Electronics is an ideal solution for operators who need a fully portable yet easy […]
Aluminum backed PCBs take the heat
When the thermal heat dissipation requirements of a design are very high, using an aluminum backed PCB is a highly effective solution. Aluminum backed designs are able to better translate thermal energy away from your design’s components and, therefore control the temperature of your design. Additionally, they are on the order of ten times more […]
Online tool for power quality simulations
Schaffner EMC introduces PQS, a Power Quality Simulation tool which allows planners, consultants and application engineers to accurately model and simulate low voltage 3-phase network topologies. This powerful online tool is easy to use, with drag and drop convenience, drop-down menu-driven functionality, and fill-in-the-blanks simplicity. It allows the simulation of power, current and voltage at […]
