에디슨이 140년 전 버린 기술, 한국이 세계 최초로 부활시켰다

Korea Revived the Technology Edison Abandoned 140 Years Ago for the First Time in the World Title Candidates Neither the U.S. Nor Japan Could Do It… Korea Overturned 140 Years of Electricity History for the First Time in the World NVIDIA Changes Electricity… The World’s First Korean Factory Ready Alternating Current Dominated for 140 Years… The Real Reason Korea Built a DC Factory DC, Defeated by Edison, Revived in Korea in the AI ​​Era Why Global Big Tech Companies Are Visiting the Cheonan Factory Technology from 140 Years Ago Revived as AI Consumes Too Much Electricity Electricity Standards Will Change in 2027… Why Korean Companies Moved First NVIDIA’s 800V Declaration: Why Money Is Flooding Korean Power Companies Uses 10% Less Electricity… The World’s First DC Factory Built by Korea After Transformers, It’s DC… A New Market Worth Decades That Korea Has Captured YouTube Description The War of Currents 140 Years Ago, Where Edison and Tesla Clashed At the time, direct current (DC) suffered a crushing defeat against alternating current (AC) because it could not freely change voltage and was difficult to safely cut off. As a result, power systems worldwide—from power plants and transmission networks to factories and home outlets—were built around AC. However, the situation has changed with the explosive growth of AI data centers. Smartphones, computers, LEDs, batteries, solar power, and AI semiconductors all operate on direct current. Yet, since the electricity supplied from the outside is AC, the power must be converted multiple times within the data center, a process that generates significant power and heat. To address this issue, NVIDIA proposed a plan to switch the power supply method for next-generation AI data centers to 800-volt DC. And on July 2nd, LS Electric launched the world's first DC Factory in Cheonan, South Chungcheong Province, which operates the entire facility using 100% DC. The company stated that it resolved the long-standing weaknesses of DC by utilizing semiconductor transformers and circuit breakers, and improved the factory's energy efficiency by more than 10% by connecting solar power and energy storage systems to DC. Not only LS Electric, but also KEPCO, LS Cable & System, Hyosung Heavy Industries, HD Hyundai Electric, LG Electronics, and the Korea Institute of Energy Research are all stepping up to build a DC industry ecosystem. However, the record of being the "world's first" does not immediately mean dominating the global market. Global power companies in the U.S. and Europe have already entered the DC data center market, and the real battle is likely to begin around 2027, when NVIDIA's next-generation servers are fully deployed. In this video, we will examine whether DC, which lost 140 years ago due to a lack of technology, can be revived in the AI ​​era, and whether Korea can translate the practical experience it has already accumulated into actual orders. What do you consider more important in the competition for new power standards? Is it the experience of operating it first, or capital strength and large-scale production capacity?
