Hon Hai Research Institute, the research arm of Hon Hai Precision Industry Co (鴻海精密), unveiled critical artificial intelligence (AI) server-related single-chip integrated circuit technology as well as high-performance power management solutions early this month in Japan, the company said yesterday.
In a statement, iPhone assembler and AI server maker Hon Hai, also known as Foxconn Technology Group (富士康科技集團), said these technologies have been recognized by the 37th International Symposium on Power Semiconductor Devices and ICs held in Kumamoto from June 1 to 5.
Hon Hai said the single chip integrated circuit technology was jointly developed by the research institute’s Semiconductor Research Center director Kuo Hao-chung (郭浩中) and his colleague Hsiao Yi-kai (蕭逸楷), National Yang Ming Chiao Tung University associate professor Wu Tien-li (吳添立) and professor Chen Po-hung (陳柏宏) and National Central University associate professor Tu Chang-ching (杜長慶).

The single-chip integrated circuit technology, developed based on the silicon carbide process platform by Hon Young Semiconductor Co (鴻揚半導體), is able to go beyond the performance attenuation limitations of traditional silicon-based circuits at high temperatures of more than 150 degrees Celsius, Hon Hai said.
Hon Hai said the latest single-chip integrated circuit technology is compatible with the existing silicon carbide component process and able to achieve more accurate analog signal processing in high-temperature environments, which is good for sensing and control systems functioning in extreme environments.
The recognized power management technology is jointly developed by the research institute’s semiconductor team and Chen’s and Tu’s research teams, Hon Hai said.
Their research efforts yielded to an LLC (inductor, capacitor, and capacitor) resonant converter controller by integrating Burst Mode control and Soft-Start functions, which can lower light load power consumption and improve system startup stability.
Hon Hai said a novel Burst Mode control solution for LLC resonant converters is aimed at achieving higher power efficiency and smaller output voltage ripple, while the new Soft-Start system can be started smoothly to avoid large current impact on components.
Ryanair, Transavia, Volotea and other low-cost airlines are feeling the financial pain from high jet fuel prices as a result of the Middle East war and are cutting flights. The closure of the Strait of Hormuz has taken a huge chunk of oil supplies off the market, sending the price of jet fuel soaring and triggering fears of shortages that could force airlines to cancel flights. Airlines are not waiting for a lack of supplies to react. “Travel alert: Airlines are cutting thousands of flights right now,” Travel Therapy host Karen Schaler said in an Instagram reel this past weekend.
MANAGING RISKS: Taiwan has secured LNG sufficient to cover 95 percent of electricity demand for next month, UBS said, describing the government’s approach as proactive UBS Group AG has raised its forecast for Taiwan’s economic growth this year to 8 percent, up from 6.9 percent previously, and said expansion could reach as high as 8.6 percent if external energy shocks are avoided. The upgrade reflects a stronger-than-expected first-quarter performance and sustained momentum in artificial intelligence (AI)-driven exports, which UBS said are providing a firm foundation for growth despite geopolitical and energy risks. Taiwan’s GDP expanded 13.69 percent year-on-year in the first quarter, the fastest growth since the second quarter of 1987, the Directorate-General of Budget, Accounting and Statistics (DGBAS) reported on Thursday. On a seasonally
The Fair Trade Commission’s (FTC) ongoing review of Grab Holdings Ltd’s US$600 million acquisition of Foodpanda Taiwan’s operations, announced on March 23, has taken on fresh urgency as industry experts warn that the transaction could embed significant Chinese cybersecurity vulnerabilities into Taiwan’s digital infrastructure through Grab’s deep ties to autonomous-driving firm WeRide (文遠知行). Less than 16 months after the FTC blocked Uber Eats’ direct attempt to acquire Foodpanda Taiwan — citing potential combined market shares of 80 to 90 percent — the emergence of Grab as the buyer has prompted questions about whether the same competitive harm is simply being rerouted
The list of Asian stocks that benefit from business partnership with Nvidia Corp is getting longer, as the region further integrates into the artificial intelligence (AI) chip giant’s business ecosystem. Just in the past week, South Korea’s LG Electronics Inc, Taiwan’s Nanya Technology Corp (南亞科技), as well as China’s Huizhou Desay SV Automotive Co (德賽西威) and Pateo Connect Technology Shanghai Corp (博泰車聯) have become the latest to rally on news of tie-ups, supply-chain participation or product collaboration with the US chip designer. Asian suppliers account for about 90 percent of Nvidia’s production costs, up from about 65 percent last year, data compiled
