Power semiconductors are a subdivision of the semiconductor industry, and although they are not as well-known as integrated circuits, their importance cannot be ignored. The "CPU" in IGBT electronic power devices and systems is a kind of power semiconductor, which is the main force of high efficiency, energy saving and emission reduction.
According to the data, from the perspective of the Chinese market, new energy vehicles are the largest application areas of IGBT, accounting for 31% of the market, followed by consumer electronics, industrial control and new energy power generation.
At present, the more obvious feature of new energy vehicles is that "the battery and motor drive system are widely used as automotive power". IGBT is an important part of the electronic control system and plays a key role in the electronic control. With the popularization of electric vehicles, it has directly driven the volume of IGBT in the new energy vehicle market, and the new energy vehicle market has become the most sufficient driving force for IGBT growth.
According to the China Automobile Association, China's new energy vehicles will reach a CAGR of 78 from 2019 to 202274%, the growth rate is at a high levelIn 2023, the residual heat of the new energy vehicle market will continue to maintain its growth momentumIt is foreseeable that the new energy vehicle market will be in a period of prosperity and rise in the next few years, and the high prosperity will continue.
New energy vehicle field:According to OfWeek, the motor drive system accounts for 15% to 20% of the manufacturing cost of the entire new energy vehicle, of which the cost of IGBT accounts for about 50% of the cost of the motor. Therefore, it can be calculated that IGBTs account for 7% to 10% of the total vehicle cost. According to data from Sina Motors, 132 IGBT tubes are used in Tesla's dual-motor all-drive Model X, with a total value of about $650.
New energy charging pile field:In the charging circuit, the battery is charged by converting alternating current to direct current, first boosting and then stepping down, each requiring an IGBT. Compared with industrial and consumer IGBTs, automotive-grade IGBTs put forward higher requirements for product safety and reliability.
As the core device in power semiconductors, IGBTs belong to a class of products that are biased towards high-voltage, medium- and low-frequency application scenarios. Generally, low-voltage IGBTs are often used in inverter white goods, new energy auto parts and other fields; Medium-voltage IGBTs are often used in industrial control, new energy vehicles and other fields; High-voltage IGBTs are often used in rail transit, power grids and other fields. Under the strong market application, the IGBT market demand is even stronger.
IGBT market demand continues to be strong:According to the 2023Q2 discrete device lead time and ** trend data released by Future Electronics in June 2023, the lead time of IGBT products of the five major global brands (STMicroelectronics, Infineon, MG Senmei, Aces and Fairchild Semiconductor) has maintained a stable level in the early stage.
The delivery cycle of international manufacturers continues to lengthen:The data shows that among the world's large manufacturers, the longest lead time for IGBT products is 54 weeks, and the delivery deadline is still relatively tight. With the intensification of Sino-US friction,Domestic terminals began to take the initiative to try to choose domestic chipsIn the past two years, the shortage of IGBT has been serious, which has opened a gap for the development of domestic chips, including IGBT.
At present, there is a huge gap between supply and demand in China's IGBT industry, with a low domestic share and a large space for substitution. Based on the relevant policy requirements of the localization of national core components"Domestic substitution" will be one of the main themes of the future development of the IGBT industry. Driven by the strong market demand, a group of R&D experts with IGBT related experience have joined the IGBT industry, and a large amount of investment funds have flowed into the IGBT industryThe industrialization level of IGBT in China has been further improved, some enterprises have achieved mass production, and the localization of IGBT has accelerated.
According to the "Analysis of the Development Status of China's IGBT Industry and Investment Prospect Research Report (2022-2029)", due toThe downstream of IGBT is mainly used in new energy vehicles, photovoltaics, wind power and other emerging fields, China's voice in the world is higher than the traditional fuel vehicles and industrial control fields in the past, so more than half of the demand in the incremental space of IGBT is in ChinaIt has created good conditions for China's IGBT manufacturers to increase their share and competitiveness, and the development of IGBT localization can be expected in the future.
