700 W digital, quarter-brick, dc-dc converter achieves 96 percent efficiency at full load
Flex Power Modules will be showing their new 700 W digital quarter brick DC/DC converter at embedded world 2023 in Nuremburg, Germany, March 14-16. The through-hole mounted BMR684 is targeted at RFPA applications needing a 50 V supply at up to 14 A for gallium nitride (GaN) or laterally diffused MOSFET (LDMOS) power amplifiers, and […]
1200 W full brick dc-dc modules deliver isolated 12V to 48V outputs
TDK Corporation announces the introduction of the TDK-Lambda brand PH1200A280 full brick DC-DC converters. Rated at 1200W with an input of 200 to 425Vdc, the modules deliver isolated, regulated 12V, 24V, 28V, 36V, and 48V outputs. The converters are very suitable for 380V DC input distributed power systems using non-isolated AC-DC power supplies. Other applications […]
Automotive-grade devices available in tiny 32.7 mm x 22.5 mm package
STMicroelectronics has introduced five power-semiconductor bridges in popular configurations, housed in ST’s advanced ACEPACK SMIT package that eases assembly and enhances power density over conventional TO-style packages. Engineers can choose from two STPOWER 650V MOSFET half bridges, a 600V ultrafast diode bridge, a 1200V half-controlled full-wave rectifier, and a 1200V thyristor-controlled bridge leg. All devices meet […]
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 […]
