高鐵為什么能跑這么快？這秘密藏在列車的下面，這是列車的變流器，相當于高鐵的大腦，而這大腦的核心則是一枚小小的芯片。指甲蓋大小的芯片組成的IGBT可以處理6500W以上的超高電壓，IGBT芯片工作時可以在短短1秒的時間內，實現10萬次電流開關動作，從而驅動高鐵飛速行駛。
High-speed why can run so fast? This secret hidden in the bottom of the train, and this is the train of the converter, the equivalent of high-speed rail of the brain, which is the core of the brain is a small chip. Fingernail chip of ultra high voltage IGBT can handle more than 6500 w, IGBT chip can work in a short span of 1 second time, achieve 100000 times current switch action, thus speeding driving high iron.
每只IGBT芯片的制造需要通過200多道工序，其中涉及半導體、機械、電子、計算機、材料和化工等多門復雜學科融合，目前在國際上能制造大功率IGBT芯片的企業也是少之又少。
Through more than 200 for IGBT chip manufacturing process, including semiconductor, machinery, electronics, computer, material and chemical industry and so on many complex subject integration, at present to produce high power IGBT chip companies in the world is rare.
這項技術誕生30多年來，一直被德國、日本等制造強國把控。三年前，中國自主研發取得突破。今天，中車的IGBT生產線，每年能制造12萬支芯片。全世界，這樣的生產線只有兩條。
The technology, which has been around for more than 30 years, has been controlled by powerful manufacturing powers such as Germany and Japan. Three years ago, China made breakthroughs in its own research and development. Today, the IGBT production line in China produces 120,000 chips a year. There are only two such lines in the world.
