Power conversion technology provides ultra-high efficiency in 500 W to 10 kW applications
Eggtronic has launched a high-performance AC/DC converter technology that provides industry-leading efficiency, reduced component count, and improved EMI performance in high-power applications requiring power factor correction (PFC). The technology, known as ClassEgg, is being demonstrated for the first time at CES 2023. Derived from the traditional boost PFC + LLC resonant power converter, ClassEgg is […]
How to control dc microgrids
Microgrids are a great way to power locations where grid connections are unreliable, though it can be tricky to control them in robust ways. Daniel Zammit, Dept. of Industrial Electrical Power Conversion, University of Malta Microgrids get a fair amount of press coverage these days thanks to their role in distributed power generation. A typical […]

Applications include railroad rolling stock and trackside equipment, robotics, power generation, and scientific research […]
Low-cost 30-W dc-dc converter features 4:1 input range
30-W dc-dc converters in the new THL 30WI series come in a standard 1×1-in footprint. This next-generation product greatly improves the “cost/performance” ratio in the 30-W, 1×1-in industry standard product area. Combined with safety approvals to the latest IEC/EN/UL 62368-1 standards, the product is a candidate for mobile equipment, instrumentation, distributed power architectures and industrial […]
1-W power modules integrate switching, control, transformer, input/output capacitors
Würth Elektronik has extended the product families of its MagI³C power modules with the MagI³C-FIMM Fixed Isolated MicroModule. It combines the features of an isolated power module with those of a MicroModule in an LGA-7 package and measures just 9 mm x 7 mm x 3.1 mm. The isolation capacitance between the primary and secondary windings […]
15-W high-density dc-dc converters come in DIP-16 footprint.
