Delta Electronics Inc (台達電) yesterday said it expects to ship 100 solid-state transformer (SST) units by the end of this year and looks forward to a more significant increase in shipments in 2028, amid soaring demand from data center operators and cloud service providers in the US and China.
The company showcased for the first time its prefabricated SST direct-current (DC) power solutions at the Energy Taiwan trade show in Taipei yesterday.
The solutions integrate SSTs, DC/DC converters and control systems to convert medium-voltage alternating current directly into the 800V DC required by data centers, it said.

Data centers account for the largest share of the company’s SST shipments, Delta vice president of the energy infrastructure business group Eton Lee (李延庭) said on the sidelines of the trade show.
Delta’s SST production capacity is mainly in China, and facilities in Taiwan are expected to be completed soon, Lee said, adding that the company plans to expand capacity in Dallas next year to meet demand there.
At the trade show, the company also exhibited its solid oxide fuel cell (SOFC) solutions.
Delta has secured an order from The Great Taipei Gas Corp (大台北瓦斯) for a 55 kilowatt SOFC system and orders from other customers, with trial production expected to begin by the end of this year, Delta general manager of the hydrogen energy business division Charles Tsai (蔡文蔭) said.
Volume shipments are expected to begin next year and expand further in 2028, Tsai said.
Delta sees data centers as the main end market for its SOFC systems, while also targeting large enterprises, semiconductor companies and other power-intensive manufacturers, he said.
The company plans to begin a trial production of the SOFC system of 5 megawatts (MW) at its Tainan Plant 2 by the end of this year, and to begin mass production at its plant in Taoyuan’s Guanyin District (觀音) in 2028 with about 5.5MW of testing capacity, Tsai said.
US-based power management company Eaton Corp also showcased a range of power management solutions at the show, including medium-voltage distribution, uninterruptible power supply systems, energy storage and circuit protection.
Among its product lines, Eaton has begun shipments of its latest medium-voltage SST, first showcased last month, starting this quarter, and expects mass production to begin next year, Eaton country manager for Taiwan and the Philippines Tony Lin (林鈺培) said.
In the longer term, the product could contribute 20 to 30 percent of Eaton’s revenue, supported by strong demand from AI data center construction, Lin said.
Clients for the SST products are mainly from China and other Asian countries, he said.
The company produces the product in the US and China and would consider manufacturing it in Tainan’s Guanmiao District (關廟) or New Taipei City’s Sijhih District (汐止) in the future, he said.
INFRINGEMENT: The investigation comes after a complaint from Vicor Corp, with the company seeking a limited exclusion order as well as cease-and-desist orders, the ITA said The US International Trade Commission (USITC) has launched a Section 337 investigation naming Taiwanese technology companies, including Hon Hai Precision Industry Co (鴻海), Delta Electronics Inc (台達電) and Quanta Computer Inc (廣達), as respondents. The Ministry of Economic Affairs (MOEA) pledged assistance if needed. The USITC said on Friday in a statement that it had voted to institute an investigation under Section 337 of the US Tariff Act of 1930 into certain vertical power delivery systems, related components and computing devices incorporating such systems. The investigation covers 20 companies from Taiwan, China, Germany and the US, the commission said, adding that it
PACKAGING PUSH: The chipmaker said that it would begin ramping up silicon interposer production in New York in the first half of 2028 to support AI systems GlobalFoundries Inc shares gained as much as 7 percent after the chip manufacturer announced a five-year, US$2 billion deal to provide US production capacity to Taiwan Semiconductor Manufacturing Co (TSMC, 台積電). Under the agreement, announced on Thursday, GlobalFoundries is to help supply components known as silicon interposers. The US company is to rely on manufacturing at its facility in Malta, New York, and said it has the option to expand capacity “as customer demand grows.” An interposer is a small layer of silicon that sits between a chip and its packaging. It is home to the wires that carry electronic signals and
A man charged along with Super Micro Computer Inc co-founder Yih-Shyan “Wally” Liaw (廖益賢) of conspiring to send cutting-edge chips to China in violation of US export controls pleaded guilty, court documents said. Ting-Wei “Willy” Sun (孫廷瑋), a former outside contractor described by US authorities as a “fixer” who allegedly aided in the sales, pleaded guilty on Thursday at a hearing in federal court in New York as part of an agreement with prosecutors, court filings showed. Prosecutors claimed the men were part of a scheme to send Nvidia Corp-powered servers to an unnamed Southeast Asian company and then divert them to
SECOND-TOP MONTH: September revenue was 0.6 percent lower month-on-month, but despite the drop, it was the firm’s highest-ever sales report for the month Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday reported record quarterly revenue for last quarter, after sales last month hit the second-highest monthly level in the company’s history. Revenue in the quarter ended last month was NT$1.49 trillion (US$46.75 billion), up 17 percent from NT$1.27 trillion in the second quarter and exceeding the combined prediction of 19 LSEG SmartEstimate analysts of NT$1.46 trillion. Last quarter’s figure — which was up 12 percent from the midpoint of last year — also surpassed the company’s July estimates of US$44.6 billion to US$45.8 billion amid surging demand for the ramp-up of its advanced 2-nanometer technology, artificial
