Realize the comprehensive optimization and matching of SiC devices with advanced motors and electronic control systems

     CISSOID, a leader in providing the high temperature semiconductor solutions needed by industries, announced: The company has reached an in-depth strategic cooperation agreement with the Department of Electrical Engineering, School of Automation, Nanjing University of Aeronautics and Astronautics, and the two sides will work together to establish a joint electric drive laboratory to jointly develop an electric control system that is fully optimized and matched with advanced motors for silicon carbide (SiC) power electronics applications. To give full play to the high frequency, high pressure, high temperature, high efficiency, high power density and other performance advantages of SiC devices, to better meet the extensive needs of industrial, aviation and new energy vehicle applications.

     SiC Advanced motor applications (such as high speed, high frequency, high power density, high temperature, etc.) require matching inverter support, but the industry has been troubled by its development difficulty. A complete inverter reference design based on silicon carbide (SiC) power generator is proposed by the joint Electric Drive Laboratory established by CISSOID and the Department of Electrical Engineering, School of Automation, Nanjing University of Aeronautics and Astronautics, which will solve the problem of SiC power system well. The planned SiC device reference design will incorporate CISSOID's SiC high voltage power modules and matching integrated gate drivers, Nanjing University of Aerospace control boards and software, ultra-low parasitic inductance DC bus capacitors and EMI filters, DC and phase current sensors and other accessories. This provides a fully integrated complete "point-and-shoot" inverter development platform for SiC advanced motor applications.

     In this way, for SiC advanced target motor applications, users can easily set parameters to fit it, only need less time to complete the calibration, so that the target motor normal operation, thus to carry out a variety of tests and experiments, for the final motor application product styling provides a basis, its simplicity will greatly save research and development time and engineering human resources, Provide strong support for users to quickly realize the productization of advanced motor applications. With the increasing maturity and popularity of SiC power systems, the application of SiC advanced motors will be vigorously promoted, and the inverter will be more "intelligent" and "silly".

     The advantages of SiC power systems such as high voltage, high frequency, high power density and high temperature lay the foundation for advanced motor applications. However, users often need to develop all the hardware themselves and then integrate third-party control software into their SiC device design environment. This traditional approach is very time consuming and engineering manpower resources, and requires in-depth knowledge of SiC based power system design as well as the design of motor control systems. In this way, the upcoming complete inverter reference design will complete these time-consuming and laborious basic engineering work for users, and users can directly use this SiC reference design platform to carry out testing work, thereby quickly realizing the product type of SiC advanced motor applications.

     After the testing and product design of SiC devices based on this "point-and-shoot" platform is completed, users can select and purchase all materials of the entire inverter solution according to the bill of materials. Or simply purchase core hardware and software components such as SiC smart Power modules (IPMs) and control boards with integrated gate drives, while other components and components such as inverter housings are available from their preferred supplier. In this way, the user can quickly integrate the inverter into the SiC target motor drive system and quickly put into the production of SiC advanced motor powertrain system.

     In summary, SiC power systems significantly outperform traditional silicon-based power devices in terms of on-resistance, blocking voltage and junction capacitance, enabling SiC advanced motor applications to achieve higher power bulk density, higher power mass density, higher switching frequency, higher efficiency, and even higher operating temperatures and reduce the complexity of the cooling system. However, achieving these higher performance places higher demands on SiC motor drive and control system design. Jointly developed by CISSOID and the Department of Electrical Engineering, School of Automation, Nanjing University of Aeronautics and Astronautics, this complete "dumb" inverter reference design is designed to reduce the design difficulty for users of SiC advanced motor applications, save development time and human resource investment, and quickly realize SiC productization.

     "Whether in research or in practical industrial applications, the industry has always pursued the perfect integration of motors and electricity. Today, industrial, aviation and new energy vehicle technologies are developing rapidly, and large-scale SiC advanced motors and electrical applications will pull and drive this pursuit to the extreme." Professor Hao Zhenyang, Department of Electrical Engineering, School of Automation, Nanjing University of Aeronautics and Astronautics. "At present, applications based on high-reliability SiC devices have greatly improved the electrical design of matched motors; However, the industry's original gate drive based on SiC devices, reliability and other aspects are still relatively weak, which has become the bottleneck to achieve high-level applications. CISDOID's high temperature semiconductor chip and packaging technology, as well as its experience in the design of highly reliable SiC devices in high-end applications such as petroleum and aerospace, will greatly help us achieve the perfect motor and electrical integration design to meet the higher needs of future industrial, aviation and new energy vehicles."

     "We are pleased to collaborate with the Department of Electrical Engineering, School of Automation, Nanjing University of Aeronautics and Astronautics; The school is a first-class scientific research institution in China, with a complete SiC scientific research and innovation platform, has undertaken a number of national important research projects, and continues to promote the development of SiC motor and electrical technology, and is widely used in the field of industry, aerospace and new energy vehicles.

     The research and development cooperation between the two parties will focus on the electronic applications of SiC devices, aiming to develop fully matched and fully optimized motor and electronic control systems, thereby providing better SiC products for industrial, aviation and new energy vehicle applications." Said Dave Hutton, CEO of CISSOID. "CISSOID has always attached great importance to the integration and development of China's semiconductor industry, and since we have raised investment from China, we have carried out extensive cooperation with Chinese companies in chip manufacturing, packaging and testing. This cooperation with China's leading scientific research institutions further highlights CISSOID's strategy of seeking broad integration into the Chinese semiconductor industry ecosystem."
