Traps to avoid when spec’ing a custom transformer
John Gallagher from Pulse Electronics recently spoke with us about some of the things design engineers and circuit designers need to know when they’re working with a company that makes transformers and inductors. He says a lot of circuit designers look at transformers as ideal transformers –there’s just a certain number of turns in the […]
Special challenges of using inductors in wide-bandgap semiconductor circuits
Dave Munguia from Pulse Electronics recently explained to us that when you’re working with gallium-nitride transistors and other wide-bandgap semiconductors, there are special challenges associated with inductors. Pulse Electronics addressed the issue in a paper they delivered at APEC 2019. Munguia says they picked five different constructions of inductors from the catalogs of different manufacturers. […]
Teardown: Simple approach characterizes modern LED bulbs
LED bulbs we examined are often simpler than those made four years ago, sometimes employing discrete transistors to handle tasks once done via chips. Leland Teschler, Executive Editor Back in 2015, we examined LED bulbs putting out the equivalent of 60-W incandescent bulbs. We recently obtained several new LED bulbs to see how things have […]
Flyback power converters, Part 2: enhancements and ICs
Power supplies and converters tend to be simple in principle, yet their actual design – including overcoming the subtle issues that degrade and impede their performance — is the real challenge. In Part 1, we looked at the flyback design and some distinct advantages along with unique idiosyncrasies. This FAQ looks at some of these […]
Basics of wireless power transmission design
Most consumer devices that transfer power over wireless links follow the Qi standard. The construction of these power transfer systems is simpler thanks to the availability of new reference designs. Contributed by IDT Inc. Examine the wireless charging setup used in the passenger compartment of most vehicles and you are likely to find a system […]
Battery self-discharge and designing for long life
Battery chemistries each have special qualities that can make certain cells impractical for varying kinds of internet-of-things applications. Sol Jacobs | Tadiran Batteries Circuit designers often find themselves in the position of trying to squeeze as much life as possible out of a battery. Today there is much discussion about boosting battery life through use […]
Flyback power converters, Part 1: basic principles
Among the many available topologies used for power-supply converters, the flyback design offers some distinct advantages along with unique idiosyncrasies. There’s a wide and diverse array of power-supply converter topologies among which to choose, each with tradeoffs in their various performance attributes and cost. The flyback design is a converter approach that has been used […]
