1 - CRRC IGBT Module Application in New Energy Vehicles
- In recent years, driven by national new energy vehicle policies, the demand for electric vehicles has been growing continuously. The market scale is huge, and development is showing an explosive trend. As a key component of EV/HEV electric drive systems, IGBT devices and related technologies have become R&D hotspots for major power semiconductor companies worldwide. They are widely used in motor control, battery charging, and low-voltage auxiliary control systems.
- The Semiconductor Division of Zhuzhou CRRC Times Electric Co., Ltd. has launched a 1200V / 600A half-bridge IGBT module (model: TG600HF12M1-S3A00) suitable for electric vehicles. This module is equipped with trench gate field-stop technology 1200V IGBT chips and soft-recovery freewheeling diode FRD chips. It has a continuous collector DC current of 600A, an operating junction temperature of 150 degrees Celsius, a maximum junction temperature of 175 degrees Celsius, and integrates an NTC. It uses enhanced DBC substrates, high-reliability solder systems, and solder layer uniformity control technology, providing higher temperature cycling capability and power cycling capability.
- The TG600HF12M1 module product has a wide Short-Circuit Safe Operating Area (SCSOA) and Reverse-Biased Safe Operating Area (RBSOA). In actual limit tests, it can withstand short-circuit currents exceeding 6 times the rated current, and overcurrent turn-off capability exceeds 4 times the rated current. It can meet the extreme application requirements of electric vehicle motor controllers.
- The Semiconductor Division is a core business unit under Zhuzhou CRRC Times Electric Co., Ltd. (Hong Kong listed, HK3898). After years of dedicated research, it has now established a complete system of automotive trench gate IGBT design – process – packaging and testing. It can support the development of current mainstream IGBT chips (trench + field-stop + carrier storage technology), and has fully mastered key packaging technologies such as automotive-grade module ultrasonic bonding, copper wire bonding, and double-sided welding. The Semiconductor Division is committed to serving new energy vehicle customers with first-class product solutions and aims to become one of the preferred suppliers of semiconductor devices in the electric vehicle industry.
2 - 50,000 CRRC IGBT Modules to Be Applied in New Energy Vehicles
- Recently, the cooperation between CRRC Times Electric Semiconductor and its customers has been upgraded again. Fifty thousand automotive IGBT modules will be installed and operated in vehicles. This deepened industrial cooperation will comprehensively promote the improvement of China’s automotive IGBT products.
- As the core power device of the electric drive system of new energy vehicles, the performance of IGBTs directly affects the overall operating performance of electric vehicles. Due to the complex operating conditions of automobiles, stringent reliability requirements, and the high technical threshold of IGBTs, this field was long monopolized by countries such as Germany and Japan. This poses significant challenges to domestically produced automotive IGBTs.
- The IGBT module products independently developed by CRRC Times Electric Semiconductor use self-produced chips. The chip uses fifth-generation TMOS+ technology, combining advanced technologies such as trench gate, field stop, and carrier storage. It exhibits low conduction loss, soft switching characteristics, and a wide Short-Circuit Safe Operating Area (SCSOA) and Reverse-Biased Safe Operating Area (RBSOA).
- In actual limit tests, it can withstand short-circuit currents exceeding 6 times the rated current, and turn-off capability exceeds 4 times the rated current. Before batch application of the product, it was successfully trial-installed in electric vehicle motor controllers. The product has been tested on actual operating routes and performs well, meeting the extreme application requirements of electric vehicle motor controllers.
- Shouldering the corporate mission and not forgetting social responsibility, CRRC Times Electric Semiconductor will continue to forge ahead on the promotion path of “CRRC Chip, Chinese Heart,” meeting greater challenges!
3 - New Energy Vehicles - CRRC Electric Injects the "Chinese Chip"
- A black box the size of a matchbox
- housing a small “chip” heart and complex “meridians” inside
- capable of freely converting and controlling electrical energy…
- This is the “heart” of new energy vehicles – the IGBT.
- As the only new energy vehicle enterprise in China with the entire industry chain from IGBT component manufacturing, key “three electric” components, power systems to complete vehicle manufacturing, the products of CRRC Electric beat with a genuine Chinese “chip.”
- “High-Speed Rail Gene” Breaking Monopoly
- IGBTs have a wide range of applications and can be called the “core chip” of the green high-end industry. From traditional power and machinery to rail transit and aerospace, its presence can be found everywhere.
- Looking back at the beginning of the 21st century, domestic IGBT module products basically relied on imports, costing billions of dollars annually. The lack of core technology caused “Made in China” to be controlled by others. It was not until 2011 that CRRC Zhuzhou Institute built China’s first 8-inch IGBT chip and module production line, breaking the foreign monopoly on high-end power semiconductor chip technology that had lasted for more than 30 years.
- In the field of electric vehicles, IGBTs play a crucial role in energy efficiency and product performance. The electric vehicle IGBT developed by CRRC and installed in CRRC Electric products is also a unique Chinese “chip” that inherits the “high-speed rail” bloodline.
- “Catching Up from Behind” Injecting a Strong “Chip” Agent
- IGBT is the core component that realizes electric drive in electric vehicles, equivalent to the heart and brain of the human body.
- Data shows that new energy vehicles equipped with CRRC Electric IGBTs reduce energy consumption by more than 20% compared to similar products. The improvement in energy utilization makes the entire vehicle more energy-efficient with a longer driving range. In terms of safety, CRRC Electric takes IGBT technology breakthroughs as the entry point, achieving the construction of a vehicle power system platform targeting functional safety, electrical safety, mechanical safety, and chemical safety, ensuring vehicle safety.
- In recent years, the scale and quality of China’s chip design industry have steadily improved, with significant breakthroughs in segmented fields. The supporting capacity of domestic chips for key areas has significantly enhanced, the construction speed of advanced process production lines has accelerated, and the packaging and testing industry is approaching the international advanced level.
- In 2017, the national key R&D plan “New Energy Vehicle Key Special Project” – the Wide Bandgap Semiconductor Motor Controller Development and Industrialization Project, led by CRRC Electric, was officially approved. The advancement of this project will bring a “chip” revolution to China’s new energy vehicles, enabling revolutionary improvements in vehicle reliability, power performance, and operating efficiency, and achieving “catching up from behind.”
- New energy vehicle manufacturers represented by CRRC Electric bravely shoulder the responsibility of industrial development, adhere to independent innovation and self-reliance, and drive the joint development of upstream and downstream technologies and industries in the industrial chain, injecting a strong “chip” agent into the development of China’s new energy vehicle industry.
