A new technical paper titled "Advances in Two-Phase Cooling for Next Power Electronics Converters" was published by researchers at ROMA TRE University, ENEA Casaccia Research Center and Sapienza University. "The proposed arrangement allows a greater extraction of the heat at a very low flow rate of the cooling fluid, even with standard industrial-grade heat-sinks, which motivates the use of ... » read more

Driving Cost Lower and Power Higher With GaN

By Anne Meixner - 06 Aug, 2024 - Comments: 0

Gallium nitride is starting to make broader inroads in the lower-end of the high-voltage, wide-bandgap power FET market, where silicon carbide has been the technology of choice. This shift is driven by lower costs and processes that are more compatible with bulk silicon. Efficiency, power density (size), and cost are the three major concerns in power electronics, and GaN can meet all three c... » read more

Power Stage Selection Considerations For High-Current Voltage Regulators

By Tammie Bard - 02 Jul, 2024 - Comments: 0

There are several key things to consider when selecting a power stage for high-current voltage regulators: What area does the power stage need to fit in? What is the continuous output current? What is the maximum peak current? This should not exceed the peak current rating of the power stage. What is the power loss for sustained output current? This can be calculated... » read more

Liquid Cooling And GaN: A Winning Combination

By Paul Wiener - 06 Jun, 2024 - Comments: 0

Data centers are facing an unprecedented transformation due to the surge in generative AI and other emerging technologies. A single ChatGPT session consumes 50 to 100 times more energy than a comparable Google search, escalating data center rack power requirements towards 200 kW or more, presenting serious challenges for operators. Cooling, in fact, takes up about 40% of the power requireme... » read more

Efficient Electronics

By Andy Heinig - 16 May, 2024 - Comments: 0

Attention nowadays has turned to the energy consumption of systems that run on electricity. At the moment, the discussion is focused on electricity consumption in data centers: if this continues to rise at its current rate, it will account for a significant proportion of global electricity consumption in the future. Yet there are other, less visible electricity consumers whose power needs are a... » read more

Optimize Power For RF/μW Hybrid And Digital Phased Arrays

By Kimia Azad - 09 May, 2024 - Comments: 0

Field-programmable gate arrays (FPGAs) are a critical component of both digital and hybrid phased array technology. Powering FPGAs for aerospace and defense applications comes with its own set of challenges, especially because these applications require higher reliability than many industrial or consumer technologies. This blog post will provide a brief history on beamforming and beam-steeri... » read more
