(1) IGBT ( insulated gate bipolar transistor ) is a BJT ( bipolar transistors ) and MOS ( insulated gate field effect transistor ) composite full -controlled voltage- driven power electronic devices, not only has high input impedance MOSFET control power is small, simple drive circuit , the advantages of high switching speed , but also has bipolar power transistor current density, saturation pressure drop , current handling capability advantages.
(2) IGBT module is composed of one or a plurality of IGBT chips are mounted on an insulating substrate , the substrate is fixed to the heat sink with a copper plate. For ease of system assembly , and to maintain the minimum lead inductance and outside the module , the module is also equipped with freewheeling diode.
(3) IGBT main applications include industrial control, consumer electronics, computer and network communications , etc., electric cars are the IGBT emerging applications, there are new requirements for IGBT .
Automotive IGBT environmental conditions and reliability requirements are shown in Table 5 to 4 . Industrial and automotive grade IGBT reliability requirements compared in Table 5 to 5 .
2 . Development of conventional IGBT foreign manufacturers mainly in Europe , USA and Japan .
Among them, Infineon, Fuji Electric , Mitsubishi Electric, Simon Kang and other companies specifically for automotive IGBT conduct research and the successful launch of products to meet demand for electric vehicles and electric vehicles be more widely used .
( A ) for the electric car launched HybridPACK Infineon IGBT module series , there are two products HybridPACK2 HybridPACKl and a maximum power of 20kW and 80kW, respectively, suitable for light mixing , all mixed cars. Another PrimePACK series IGBT module that can meet the higher power requirements , can be used in trucks and buses .
( 2 ) Fuji Electric products in the Toyota Hybrid Camry [ Review Photo Forum ] on the application , the product is suitable for 10kW ~ 120kW drive motor system.
( 3 ) The main production Mitsubishi IGBT modules , discrete devices manufactured by Renesas Semiconductor ( Mitsubishi Electric and Hitachi Joint Venture ) production . Its automotive IGBT products have been applied to other auto manufacturers Honda and Toyota hybrid cars.
( 4 ) Simon Kang (Semikron) launched without welding IGBT modules , using Infineon's chips for electric vehicles using 22 ~ 150kW motor controller.
3 . Development Status of IGBT ( 1 ) of IGBT has just started, mainly through outsourcing IGBT chip , the traditional industry standard module package , mainly micro- enterprises Jiangsu , Nanjing Silver Mao, Jiaxing Star , Weihai Star [ Review Photo Forum ] Jia , Xiamen Hongfa other companies. Another part of the industry chain downstream business through the acquisition of intervention power semiconductor devices, such as BYD and South car era . Some companies have begun to study automotive power IGBT modules.
( 2 ) R & D capability of IGBT core technologies including chip and module packaging two aspects . IGBT chip design companies basically have the ability , but the lack of manufacturing capacity, industry Shangdaishiri ; enterprises through the introduction of foreign equipment and returning talent , has now basically have modular design , packaging , testing analysis capabilities , enabling BT module IG Juan the independent production .
( 3 ) the case at this stage of the IGBT module products generally focused on 600V and 1200V, voltage level higher product research and development , the main application areas for industrial inverters, welders, induction heating.
