Decrypt the core of new energy vehicle motor drive-IGBT
For new energy vehicles, battery, VCU, BSM, and motor efficiency all lack room for improvement. The most room for improvement is the motor drive part, and the core component of the motor drive part IGBT (Insulated Gate Bipolar Transistor) Type transistor chip) is the most important thing.
The motor drive control system determines whether the new energy vehicle can run safely and reliably, and is the core of the drive system. The development of electronic control system includes software and hardware design. The core software is generally developed by the vehicle manufacturer, and the hardware and underlying driver software can optionally be provided by the auto parts manufacturer. The motor control system is mainly composed of inverter (the main component is IGBT power module), inverter driver, power module, central control module, soft start module, protection module, heat dissipation system signal detection module, etc., of which IGBT accounts for the entire controller cost Of 40-50%. At present, IGBT has not yet been localized, and it is monopolized by foreign countries. Mainly foreign companies such as Toyota Industries, Mitsubishi, Meidensha, Nichicon, Nissan, Magna, Toshiba, Bosch, etc. produce inverters for electric vehicles. The domestic technology needs to be further improved. Some other key components, such as high-performance silicon steel sheets and insulating materials, are also mainly dependent on imports. If domestic technological breakthroughs are achieved, there will be a huge market space.
Based on the success of the past eight new energy vehicle forums, the 9th China International New Energy and Smart Vehicle Forum 2019 hosted by CM Business Consulting (Shanghai) Co., Ltd. will be held in Shanghai from April 2 to April 3. held with grandeur. The powertrain of this forum involves the relatively new progress of electronic control chip IGBT in the field of new energy vehicles, and will invite global vehicle manufacturers, IGBT technology vendors, electronic control integrators, motor suppliers, and core technologies. Service providers and government officials, etc. At the same time, there are a total of 8 forums, CEO TALK, award ceremony, one-on-one negotiation and cocktail party, and nearly 900 industry professionals will work together on the challenges, opportunities and countermeasures faced by the new energy automobile industry for a period of 2 days. Constructive and strategic discussions.
