"The release of this 3.3 kV MOSFET voltage node in two complementary footprints was a strategic decision," said Guy Moxey, vice president of Wolfspeed's Industrial & Energy business. "We understand the urgency our customers are facing to scale power infrastructure, and these two families enable both established grid-scale players and emerging players with modular architectures to move quickly. We are giving engineers the tools to build the grid of tomorrow, today — and only by working together can we successfully address the surging demand for power and unlock the full potential of AI and electrification."

Your System — Your Choice

The two 3.3 kV families enable design engineers to reduce power stages and move to a 2-level topology for 2 kV and higher DC-link architectures — with the choice of baseplate and baseplate-less SiC power modules.

The high-power half-bridge baseplate SiC power module (LM platform) is designed for >800 amp (A) applications and optimized for demanding converter topologies used in solar, grid-scale energy storage, and wind-power infrastructure.

The scalable full-bridge baseplate-less (part of the Wolfspeed WolfPACK® family) SiC power module is engineered for modularity, offering flexibility to configure multi-level, series-stacked, or parallel converter architectures with consistent, matched performance — and is optimized for solid-state transformers (SSTs) and modular renewable energy infrastructure.

Purpose-Built for Continuous 24/7, 2 kV+ DC-Link Operation

Both families are engineered for the relentless demands of always-on infrastructure. The Wolfspeed WolfPACK® module leverages cutting-edge sintered die attach and epoxy encapsulant material to deliver a significant improvement in power cycling performance over standard silicon gel encapsulated modules. Similarly, the baseplate module achieves improved system durability and power cycling through advanced packaging technology featuring sintered die attach and a copper die-top system. Both families feature Gen 4 technology with improved cosmic ray susceptibility.

“Amperesand is focused on critical power delivery from medium voltage to AI rack, requiring best-in-class reliability, power density, efficiency, and cost effectiveness,” said Brian Dow, Chief Executive Officer at medium-voltage solid-state transformer manufacturer Amperesand. “The latest advances in SiC technology enable maximum reliability for high variability AI factory loads, while unlocking optimized packaging that drives previously unachievable costs and best-in-industry power density and efficiency. Wolfspeed is driving innovation, scale, and quality that is ideally suited for demanding solid-state transformer critical power solutions.”

Smaller Size – Lower System Cost

The Wolfspeed WolfPACK® module enables solid-state transformer systems to deliver over 50% footprint reduction compared to traditional equipment through improved switching performance and system architecture improvements. Read how Amperesand is engineering for industry-leading space savings and 20-30-year lifetime for their 6+ MW medium voltage SST using the 3.3 kV Wolfspeed WolfPACK® solution here.

The new high-power baseplate module delivers up to 42% improvement in switching losses over other market-available SiC solutions and greater than 90% over IGBTs — both measured at 125°C on a 1.8 kV bus in the same package.

Both families achieve improved switching over temperature, reducing magnetics and EMI filter sizes, ultimately leading to system power density and reduced system costs.

NEW YORK (AP) — Walmart delivered another quarter of impressive sales with speedy deliveries and low prices becoming a strong magnet for people across the income spectrum that are spending more on almost everything, particularly gasoline.

Yet like other major retailers posting financial results this week, Walmart was cautious about the rest of the year given the current economic uncertainty. On Thursday, it issued a forecast for the current quarter that was weaker than what Wall Street had been expecting.

Shares slipped about 7% Thursday.

Walmart has resonated with many Americans who are increasingly careful about where they spend their money as inflation takes a bigger bite out of paychecks, notably gasoline which has soared since the start of the Iran war in late February. Walmart can serve as a barometer of consumer spending given its vast customer base. More than 150 million customers are on its website or in its stores every week, according to Walmart.

One telling shift during the quarter that captures the stress many Americans are feeling: The number of gallons that customers put in their cars during visits to U.S. Walmart and Sam’s Club gas stations fell below 10 for the first time since 2022, which was the midst of the COVID-19 pandemic.

“That’s an indication of stress,” said Chief Financial Officer John David Rainey.

Walmart touted strong sales that were fueled by online shopping on Thursday.

Comparable sales at U.S. Walmart stores rose 4.1% during the three-month period ended April 30. Walmart’s U.S online sales rose 26%, the company said.

Walmart’s promise of lower prices, faster delivery and a refresh of its merchandise has attracted wealthier shoppers. The biggest gains in market share for Walmart are coming from households with annual income over $100,000. That shift is taking place as lower-income shoppers become more entrenched in what economists collectively call a K-shaped economy.

“We see with our customers that the high-income customer is spending with confidence into many categories, while the lower income consumer is more budget conscious and perhaps navigating financial distress,” Rainey told analysts on Thursday.

Rainey told analysts that higher fuel prices took a bite out of profits as it was forced to absorb higher transportation costs. And while the company is focused on offering low prices, Walmart may raise prices later if fuel costs remain high, he said.

U.S. retailers have spent months navigating an uncertain economic environment, from President Donald Trump’s tariffs to the impact of soaring gasoline prices due to the war. The average price for a gallon of regular gasoline raced higher this week and did so again overnight. Gasoline prices are about 45% above where they were at this time last year.

Based on quarterly financial reports from Walmart, Target, Home Depot, Lowe's and TJX, shoppers are cautious but still spending, helped by more generous tax refunds. Yet there is a widespread belief among economists that once those refunds dry up, shoppers will pull back on spending. Consumer spending is the dominant economic engine for the U.S., and retreat would have broad implications for the U.S.

Target reported the largest jump in comparable sales in four years Wednesday, but a cautious outlook overshadowed rather convincing evidence that changes under the company’s new CEO are landing solidly with customers. Target raised its annual revenue outlook Wednesday, but it was still below the pace of its first quarter this year.

The nation’s two largest home improvement retailers Home Depot and Lowe’s reported strong sales, but both companies said that customers are putting off larger home projects.

“I think, overall, this has been the most difficult housing market that I’ve faced in this business since the financial crisis,” Lowe’s CEO Marvin Ellison said this week.

Walmart, based in Bentonville, Arkansas reported first-quarter earnings of $5.33 billion, or 67 cents, for the quarter ended April 30. Adjusted per-share results were 66 cents, matching the 66 cents that analysts expected, according to FactSet.

For the year-ago quarter, the company reported net income of $4.48 billion, or 56 cents per share.

Sales rose 7.3% to $177.75 billion in the fiscal first quarter, above the $174.84 billion that analysts predicted.

Walmart said higher fuel prices took a bite out of profits as it was forced to absorb higher transportation costs.

The company highlighted its speedier deliveries, which is driving more shoppers to buy more often. Rainey said that roughly 60% of U.S. online deliveries arrive at customers' homes in 30 minutes or less.

For the second quarter, Walmart expects sales to be 4% to 5% higher than the same period a year ago. It also expects per-share profit to be between 72 cents and 74 cents. Analysts had been projecting per-share earns of 75 cents on sales of $186.2 billion, according to FactSet.

Walmart stuck to the annual guidance that it issued in February.
