30-second overview: In 1971, a refugee student who had left his parents in Fujian at age 13 and come to Taiwan with his uncle raised NT$300,000 to found Delta Electronics in Xinzhuang.
By 1983 it was mass-producing switching power supplies; by the mid-1990s it was the world's largest power supply manufacturer; 2025 revenue reached NT$554.9 billion.
His name also flew into space: asteroid 168126 is named "Chengbruce."
On April 4, 1971, on Min'an Road in Xinzhuang Township, Taipei County. Cheng Chung-hua, in his thirties, left American firm TRW (Thompson Ramo Wooldridge), raised NT$300,000, and established Delta. The founding team numbered only 15, producing TV coils and intermediate-frequency transformers1. The factory was a small house left behind by a young man preparing to study abroad; his father let Cheng pay rent at month-end with no deposit2. This young man, who at 13 had left his parents due to the Chinese Civil War and come to Taiwan with his uncle as a refugee student3, did not yet know he was launching a company that would transform the power industry.
Fifty-five years later, from personal computers to cloud data center server power supplies, to electric vehicle powertrain components, Delta Electronics has quietly become the "invisible infrastructure" of modern digital life.
But the most astonishing part of this story is not the revenue figures—it is how one person turned "environmental protection" from a moral slogan into commercial competitiveness.
The Taiwanese Entrepreneur in Space
On April 1, 2006, the Lulin Observatory at National Central University discovered an asteroid, designated 168126. In 2008 it was officially named "Chengbruce"4—it will orbit the cosmos forever, carrying a Taiwanese entrepreneur's name.
This was not vanity purchased with money. Cheng Chung-hua donated to sponsor the Lulin Observatory's two-meter telescope project, rebuilt the observatory at National Central University's Science Building I, and established the "Delta Electronics Young Astronomer Lecture." During the 2009 "International Year of Astronomy," he served as a "Star Ambassador"5.
Why would a power supply manufacturer invest in basic science? Cheng said he loved astronomy, moved by the vast sky: "Compared to the universe, humanity is truly tiny."5
📝 Curator's Note
Asteroid "Chengbruce" orbits the Sun once every ~1,510 days, about 4.1 years4. The naming citation cites his use of energy-saving technology and public speaking to protect the natural environment, and his promotion of higher education in Taiwan.
This long-term thinking explains why Delta has maintained a half-century lead in technological innovation.
From TV Parts to AI Era's Power Steward
The story returns to that Xinzhuang factory. When Delta was founded in 1971, it mainly produced TV coils and intermediate-frequency transformers—components for the black-and-white TV era. Cheng Chung-hua had studied electrical engineering theory at Cheng Kung University, worked as an aerospace instrument engineer at Asia Aviation, then joined American firm TRW as an engineer3.
What truly changed Delta's destiny was the 1983 mass production of switching power supplies6. Cheng recalled that at the time TVs, refrigerators, washing machines, and air conditioners were selling rapidly, Taiwan's power grid couldn't cope and blackouts were frequent. Sitting at home, he thought he should make products to change this situation, and began researching power supply units7.
Switching power supplies were compact and high-efficiency. The earliest power supplies Delta supplied to Apple Computer had 65% energy conversion efficiency; later server power supplies reached 96%8. When personal computers took off, Delta happened to be perfectly positioned.
A 2004 Business Weekly report wrote that as early as 1996, Delta was already the world's largest power supply manufacturer9.
The corporate mission "Environmental Protection, Energy Saving, Love the Earth" was set by Cheng Chung-hua when he decided to pursue switching power supplies; Delta's switching power supplies began shipping in 1983, and by 2000 all power supply products exceeded 90% efficiency10. In an era before ESG was widespread, writing energy saving into the corporate mission looked like neglecting business.
Decades later, this proves to be Delta's wisest strategy.
The Invisible Yet Omnipresent Power Empire
What scale of business empire is Delta Electronics today?
In 2025, Delta's full-year revenue reached NT$554.9 billion, up 31.76% year-on-year, a historic high11. Delta's official website lists 165 operating locations, 55 production sites, and 73 R&D centers12.
| 2025 Q4 | 2025 Full Year |
|---|---|
| Revenue NT$161.6B (record) | Revenue NT$554.9B |
| Up 41.51% YoY | Up 31.76% YoY |
Even more striking is the change brought by the AI wave: in the first three quarters of 2025, AI-related power supply products accounted for 23% of Delta's total revenue, growing six-fold from the previous year; AI server power supplies accounted for roughly half of Delta's server power supply revenue11.
⚠️ Contested View
Some analysts believe Delta is over-dependent on the AI boom and may face overcapacity when the AI bubble bursts.
But Delta management insists AI brings structural demand, not cyclical hype.
New Opportunities and Challenges Under the AI Wave
As AI applications explode, global data center power demand is growing sharply. Tech giants are building hyperscale data centers measured in gigawatts (GW). A 1 GW facility running at full load for a year consumes 8.76 billion kWh.
The challenge lies in the speed of technological evolution. Next-generation AI chips impose unprecedented demands on power management. Delta is developing 800-volt high-voltage DC power systems and ±400-volt DC systems, targeting mass production in H2 202611.
According to the Taipei Times, Delta's factories in Taiwan, Thailand, and the U.S. are running at full capacity; after adding three new plants in Thailand by end-2025, capacity will continue expanding this year11.
But Delta's competitiveness lies not only in capacity, but in system integration capability. It is not merely a component supplier, but a systems integrator providing complete solutions. When automakers need EV powertrain systems, Delta can provide complete solutions from on-board chargers to drive motors. When data centers need energy-saving retrofits, Delta offers one-stop service from power supplies to air conditioning.
The Business Philosophy of Energy Saving: Turning Environmental Protection into Competitiveness
Delta's most astonishing figure is not revenue, but its contribution to global energy saving. Cheng Chung-hua says from 2010 to 2023, Delta's high-efficiency energy-saving products and solutions cumulatively helped global customers save approximately 45.5 billion kWh, equivalent to carbon reduction of nearly 23.84 million metric tons13.
The key is that Delta turned sustainability from a slogan into a business model.
In March 2021, Delta announced it had joined RE100, committing to 100% renewable energy at global sites by 2030—the first high-tech manufacturer in Taiwan to make this pledge14 (TSMC joined in 2020 as Taiwan's 5th company15). Internal carbon pricing started earlier: 2014 introduced a non-charging "shadow price"; from 2021, an actual internal carbon fee of US$300 per metric ton was levied on business units; the year after implementation carbon emissions fell 13.5%, and by 2023 a further 39%16.
📊 Data Source
According to CSR@CommonWealth, the collected carbon fees also help Delta invest in renewable energy.
One subsidiary received a carbon fee bill in 2021 exceeding expectations, decided to apply for over US$20 million for carbon reduction projects,
and the following year emissions fell 38%, with subsequent carbon fees dropping sharply16.
According to estimates by energy and climate policy firm Energy Innovation, every 1% improvement in server power supply efficiency saves roughly 1 megawatt per data center17. This is not moral persuasion—it is mathematics. In an era of rising global energy costs, energy saving is competitiveness.
The Contract Manufacturing Giant's Brand Breakout
Delta's greatest challenge is finding balance between contract manufacturing mindset and brand innovation. In the 1980s–2000s, it was primarily an ODM supplier to multinationals, bringing stable orders but limiting its control over technological development.
The turning point came in the 21st century. Delta began heavily investing in its own "DELTA" brand while maintaining contract manufacturing. This dual-track strategy let it maintain cash flow while accumulating brand value.
In the global industrial power supply market, Delta ranks alongside Japan's TDK Lambda as a major supplier18. These achievements prove Taiwanese enterprises are not limited to contract manufacturing—they can also build brand advantages in technology-intensive fields.
💡 Did You Know
The 1 MW solar system on the roof of the 2009 Kaohsiung World Games Main Stadium was built by Delta1.
8,844 solar panels covered the roof designed by Toyo Ito,
then the world's largest single-building solar photovoltaic system19.
The Inspiration of a Drop of Wastewater
Cheng Chung-hua's environmental conviction came from a personal experience while working at TRW before founding Delta. The company sent him to the U.S. for training; he discovered American factories collected tin-plating wastewater, neutralized it with chemicals, then discharged it. Back in Taiwan, he found the same factories did not do this because Taiwan's laws did not require it. That shock made him think: when I start my own business, "at the very least, I myself must do it right!"7
Fifty years later, that thought became Delta's core competitiveness. As the world pursues net-zero emissions, Delta's energy-saving technology is not just product—it is a tool for humanity to address climate change.
Environmental protection is not a cost, but a source of competitiveness. This sounded like idealism in 2000; in 2026 it is business common sense.
The Wisdom of Succession
In 2012, 75-year-old Cheng Chung-hua announced his retirement at the shareholders' meeting. Hai Ying-chun succeeded as chairman, and eldest son Cheng Ping became CEO6. This is a rare smooth succession case in Taiwan's business world. After completing a management degree in the U.S. at age 27, Cheng Ping started at Delta's China factories as a shift supervisor, sleeping in dorms and eating at the staff canteen like any other employee20.
Under Cheng Ping's generation, Delta continues to deepen the "Environmental Protection, Energy Saving, Love the Earth" mission while strengthening digital transformation and AI applications. In December 2024, Delta launched its Net Zero Science Laboratory in the Tainan Science Park—Taiwan's first megawatt-class water electrolysis hydrogen production and hydrogen fuel cell testing platform.
This shows Delta is not merely executing existing strategy, but preparing for the next generation's energy revolution.

An Era in Microcosm
Delta Electronics' story is a perfect microcosm of Taiwan's manufacturing transformation and upgrading. It demonstrates how Taiwanese enterprises moved from contract manufacturing mindset to technological innovation, from cost competition to value creation, from local operations to global deployment.
More importantly, Delta proved that "manufacturing" and "sustainable development" are not opposed—they can mutually reinforce. In an era of global net-zero pursuit, the green technologies Delta began laying out 20 years ago have become its greatest moat.
A refugee student who left home at 13 for Taiwan used half a century to build a power empire, and sent his own name into space.
This story tells us Taiwan is not just an "Island of Manufacturing," but an "Island of Innovation." In the next generation's technological revolution, we have reason to expect more such Taiwanese legends.
As AI reshapes the world and climate change rewrites business rules, Delta Electronics is already ready. It has used 50 years to prove one thing: true competitive advantage lies not in making things cheaper, but in making them smarter.
In a world needing higher efficiency, greener solutions, and greater intelligence, Delta Electronics is not just a model for Taiwanese enterprises—it is a driver of human technological progress.
