高铁为什么能跑这么快？这秘密藏在列车的下面，这是列车的变流器，相当于高铁的大脑，而这大脑的核心则是一枚小小的芯片。指甲盖大小的芯片组成的IGBT可以处理6500W以上的超高电压，IGBT芯片工作时可以在短短1秒的时间内，实现10万次电流开关动作，从而驱动高铁飞速行驶。

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芯片的制造需要通过200多道工序，其中涉及半导体、机械、电子、计算机、材料和化工等多门复杂学科融合，目前在国际上能制造大功率IGBT芯片的企业也是少之又少。

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.

这项技术诞生30多年来，一直被德国、日本等制造强国把控。三年前，中国自主研发取得突破。今天，中车的IGBT生产线，每年能制造12万支芯片。全世界，这样的生产线只有两条。

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.
