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

In today's world, semiconductors are essential components of our everyday lives and the backbone of our economies. From the devices we use to communicate to the machines that power our factories, semiconductors are the building blocks that enable digitalization and decarbonization. However, public and policy debates about semiconductors often focus solely on their smallest feature size, measure... » read more

What’s Next For Power Electronics? Beyond Silicon
By Emily Yan - 29 Feb, 2024 - Comments: 0

For more than half a century, silicon has been the bedrock of power electronics. Yet as silicon meets its physical limitations in higher-power, higher-temperature applications, the industry’s relentless pursuit of more efficient power systems has ushered in the wide bandgap (WBG) semiconductors era. The global WBG semiconductors market reached $1.6 billion in 2022, with an estimated CAGR of ... » read more

New Issues In Power Semiconductors
By Ed Sperling - 26 Feb, 2024 - Comments: 0

The number of challenges is growing in power semiconductors, just as it is in traditional chips. Thermal dissipation and gradients, new design rules, and layout issues need to be considered, especially in the context of higher voltage and increased performance demands. Roland Jancke, design methodology head in Fraunhofer IIS’ Engineering of Adaptive Systems Division, talks about issues in int... » read more

Using OCD To Measure Trench Structures In SiC Power Devices
By Nick Keller - 08 Feb, 2024 - Comments: 0

You don’t have to be a dedicated follower of the transportation industry to know it is in the early stages of a significant transition, away from the rumbling internal combustion engine to the quiet days of electric vehicles. The signs of this transition are right there on the streets in the form of electric-powered buses, bikes and cars. The road to our electric future is before us, but we w... » read more
