Germany used to be one of the global leaders in high-speed rail technology, and it once mastered the core technology of high-speed rail. At that time, it earned 1 billion in revenue from China with the core technology it mastered. However, China's technology industry persisted and finally broke through. In addition to its monopoly, China's high-speed rail technology has even begun to be exported overseas.
More than 20 years ago, Western media ridiculed China's high-speed rail for suffering from a "heart attack". The reason was that at that time, IGBT chips, one of the core chips of high-speed rail, were controlled by giants such as Siemens in Germany. IGBT chips are important chips for high-speed rail, which can accurately control high-speed rail The high current and voltage ensure the steady acceleration of the train, smooth running, accurate inbound and so on, so it is known as the heart of the high-speed rail.
Siemens and other German companies took advantage of their monopoly. They sold a chip for 20,000 yuan, and Germany earned 1.2 billion yuan from China every year. At the time when they were monopolized by them, Chinese high-speed rail companies had to accept , This is the helplessness of the high-speed rail industry.
China's high-speed rail industry learned from the painful experience. After that, it took several years to concentrate the manpower and material resources of all parties to quickly develop domestic high-speed rail IGBT chips, breaking the German monopoly. Since then, China's high-speed rail has adopted domestic IGBT chips. The IGBT chip has also reached the German technical standard. After more than ten years of operation, the domestic IGBT chip has proved the strength of the domestic chip with its reliability and durability.
The successful research and development of domestic IGBT chips has enhanced the self-research strength of domestic high-speed rail, and also has autonomy, so that domestic high-speed rail can go to overseas markets and is no longer restricted by overseas technology. Broad overseas market.
IGBT chips are not only used in high-speed rail, but also widely used in the automotive industry, especially with the rise of new energy vehicles, the demand for IGBT chips has surged, and domestic auto companies have also repeated the success of high-speed rail IGBT chips.
BYD is a leader in domestic new energy automobile companies. It began to develop IGBT chips a few years ago. Now BYD's own cars use self-developed IGBT chips. Industry insiders pointed out that BYD's IGBT chips have reached the industry's advanced level. Even foreign-funded enterprises have recognized it, but BYD stubbornly stated that its IGBT chips will only be provided to domestic counterparts and will not be supplied to foreign-funded enterprises.
IGBT chips are the epitome of domestic chips. In recent years, Chinese chips have made great achievements, breaking overseas monopoly in memory chips, analog chips and other industries. The rapid development of memory chips has caused memory chips in the United States and South Korea to suffer. Since the second half of last year, their memory chip companies have successively fallen into losses. Micron’s revenue in the first quarter was only US$4 billion and its loss was as high as US$2.3 billion. Samsung’s profit in the first and second quarters of this year was due to the loss of its memory chip business. Both fell by more than 90%.
The breakthrough of these domestically produced chips has enhanced the competitive advantage of Chinese manufacturing, avoided being continuously controlled by others, and improved the self-sufficiency rate of domestically produced chips. Since last year, the number of chips imported by China has decreased by more than 140 billion. Chip substitution has caused huge losses to the overseas chip industry, and I am amazed at the great progress of Chinese chips.
Obviously, Made in China, once looked down upon by countless people, is no longer synonymous with cheap and low-end. The technological breakthroughs in China’s chip industry are unstoppable. The competitive advantage of Made in China continues to increase. Chinese brands have begun to go global, and the world has gradually seen it. The strength of Chinese manufacturing.
