CISSOID and IEE/CAS to jointly develop SiC power solutions

CISSOID and Institute of Electrical Engineering of Chinese Academy of Sciences established a strategic partnership to jointly develop solutions for the extensive applications of SiC power devices

Mont-Saint-Guibert, Belgium and Beijing, China - June 10, 2019 - CISSOID, the leader in high temperature semiconductors for the most demanding markets, announced that it has established a strategic partnership with Institute of Electrical Engineering of Chinese Academy of Sciences (IEE/CAS). The two parties will jointly develop systems based on the silicon carbide (SiC) power modules for overcoming technical issues and implementing the advantages of SiC power devices such as high temperature resistance, high voltage resistance, high energy density and high efficiency. The cooperation is expected to promote the extensive applications of SiC power devices in new energy vehicles.

 

In recent years, SiC power devices have gradually replaced traditional silicon devices in some fields with their diversified performance advantages. Meanwhile, new energy vehicles have been growing rapidly around the world. It drives the continuous expansion of the market for SiC devices. At present, the world's top OEMs including Tesla and Toyota have started the early adoption of SiC power devices in the field of new energy vehicles. However, in automotive applications, SiC devices need drivers’ full supports for high temperature resistance and exceptional demanding protection mechanisms to fully exert their advantages. Based in Belgium, CISSOID is a leading company in high temperature semiconductor solutions. It has a portfolio of components and drivers, which have been proven in high-end fields like aviation and aerospace, petroleum and automotive. These products feature high temperature resistance, high reliability and high robustness and have been used for more than 10 years. They enable SiC power modules to fully release their performance in the systems, helping new energy vehicles to increase their power operation level and driving mileage.

 

IEE/CAS is a national research institution oriented to the development of electrical science and engineering. It is positioned on the development of high technologies in electric energy and the frontier research of electrical science, as well as occupying a distinctive position in China’s energy and electrical fields. IEE/CAS has a history of more than 20 years in the research of electric vehicles and has undertaken and completed dozens of important scientific research tasks in electric vehicles for the nation and regions.It has taken the lead in basic theory research and key technology development of in-vehicle motor drive systems with high power density in China. Its related products and technologies have been successfully used in the demonstration projects such as Beijing Olympics 2008 and Shanghai World Expo 2010, and have high reputation and wide influence in international peers. In recent years, IEE/CAS has taken the lead in researching the wide bandgap semiconductor, and has successfully developed direct cooling SiC hybrid power modules, new indirect cooling film capacitors and the prototype of full SiC and high power density motor drive controller, which have independent intellectual property rights. Some key indicators of these products like power density and efficiency have reached the international leading level. Through this cooperation, CISSOID and IEE/CAS will generate powerful synergy by combining respective advantages, and jointly develop high-quality systems based on SiC power modules to help China's new energy vehicles to achieve faster and better development.

 

The production and sales volumes of new energy vehicles in China increased by a large margin in 2018, and both of them exceeded 1.25 million units. This will powerfully promote the development of China’s SiC power device market. Over the past years, IEE/CAS has heavily invested in the research and development of new energy utilization, in which new energy vehicle is an important part. The cooperation with CISSOID on the development of systems based on SiC power modules is a key step for us to promote the growth of new energy vehicles in China.” Said Xuhui Wen, Researcher of IEE/CAS. “New energy vehicles have strong demands on high-efficiency, small-size, high-temperature-resistance SiC devices and their drivers. CISSOID's high temperature drivers and high temperature packaging technology used for many years can help SiC devices to achieve high temperature resistance and high energy density at the system level, and greatly improve the overall reliability of electronic control system.”

 

IEE/CAS is a top research institution in China. Their research on new energy vehicles accords with our thoughts. I highly expect that the research of two parties can push the efficiency and energy density of SiC power modules to new level. CISSOID will leverage its proven, industry-leading high-temperature driver chips and high-temperature packaging design team to fully support this research and development collaboration and solve the tough technical issues in applications of SiC devices, implementing the extensive and in-depth applications of SiC power modules in new energy vehicles.” Said Mr. Dave Hutton, CEO of CISSOID. “CISSOID is highly focused on the development of China's new energy vehicles and the integrated development with China's semiconductor industry. We have already absorbed investment from China, and have started extensive cooperation with Chinese companies in the areas of chip fabrication, packaging and testing. The joint development with a top research institution in China further confirms CISSOID’s strategy of broad integration into China's semiconductor industrial ecosystem.”

 

According to Yole Development, in the past few decades, the average Tj (junction temperature) of power semiconductors has always risen due to the drive of market demands, technical advancement, design improvement and other factors. It has been increasing from 100 in 1980 to 150 in 2018. On the one hand, this phenomenon shows that the quality and reliability of power devices get better and better, and on the other hand, it also reflects the whole industry’s continuous pursuit of high power density. According to Yole’s prediction, the requirement on Tj of power semiconductors will reach and exceed 175 in few years. This is directly related to the popularity of third-generation semiconductor power devices (SiC and GaN) and the market demands for high power density designs. The same is true for new energy vehicles. The adoption of SiC devices can provide advantages such as high frequency and low internal resistance, and fully improve energy efficiency, but requiring good cooperation from high temperature resistance drivers. This powerful alliance between CISSOID and IEE/CAS will utilize the industry-leading high temperature resistance drivers to fully exert the advantages of SiC power devices, strongly boosting the development of new energy vehicles.
