【摘要】 近两年国内汽车的价格和竞争压力都在增大,行业利润率和销量已驶入下行通道。这一背景下,国家下发了一系列补贴政策鼓励新能源汽车发展,使之成为市场新宠。“十三五规划”报告明确提出,“大力发展和推广以电动汽车为主的新能源汽车,加快建设城市停车场和充电设施。”这意味着,电动汽车相比其他新能源能源汽车将成为该领域研究和发展的主力地位。IGBT驱动模块作为新能源汽车“三纵三横”发展战略中的一环,直接关系系统的可靠性。同时,驱动板作为高压主电路IGBT模块和低压PWM控制驱动部分的中转站,同时承担着驱动IGBT模块和保护该模块的任务,在IGBT工作中起着举足轻重的作用。本文以设计和研究IGBT驱动板为目标,主要分为以下几个方面：首先,结合IGBT的市场和在纯电动汽车中的应用,概述驱动模块发展现状。对具有代表性的产品进行了归纳和对比。以IGBT为研究对象,分析其结构,原理,失效因素等,作为驱动板驱动、保护要求和总体结构的依据。并用Saber软件创建了的一款IGBT的模型；其次,结合可行性方案利弊分析,设计了IGBT驱动板的电路图。电路主要分为母线电压的检测电路,IGBT及驱动板的温度检测和报错电路,隔离电源电路,驱动主电路。对驱动主电路一系列IGBT保护功能进行了原理分析。对隔离电路中的变压器进行了设计,搭建了驱动芯片内部逻辑结构,随后用Saber, Pispice对以上模块进行仿真,证明原理正确性。最后,为使驱动板能有效的抵御各层间信号的干扰,减少寄生电感,提高稳定性,分析了布局布线等要求,用Cadence Allegro设计和绘制了六层板。随后用相应的软件,进行了SI、PI仿真。验证信号质量的可靠性,对问题信号进行了优化。仿真PCB谐振和电流密度,对谐振点噪音较高的位置进行优化。为提高设计的驱动板可靠稳定性提供理论依据。更多还原

【Abstract】 The prices and competitive pressures of the domestic cars are increasing recent years.Industry profit margins and sales have been entering the downstream channel.Under this background,the state issued a series of subsidy policies to encourage the development of new energy vehicles,which make it to become a new darling of the market.The"Thirteenth five year plan report"made it clear that "Vigorously develop and promote electric car of new energy vehicles,to speed up the constrction of urban parking and charging facilities."It means that, compared to other new energy vehicles,electric car will become the main position in the field of research and development.As a part of "Three vetical and three horizontal"development strategy,IGBT driver is the transit station of high voltage IGBT module and low voltage PWM control,act both as driver and protector.In this paper,make IGBT driver as research and design target,mainly divided into the following aspects:First of all,combined with IGBT market and application in new energy vehicles,draw an overview of the development status.Summerize and compare representative products.Taking IGBT as the research object,analysis of structure principle,failure factors,then propose the protection requirements and the overall structure based on it. Created an Infineon IGBT model with Saber software as well.Secondly,combining with the pros and cons of feasibility plans,desiged circuit diagram of IGBT driver.The circuit consist of bus voltage detection circuit,both IGBT and IGBT driver board temperatue detection and fault report circuit,Isolation power supply circuit,main driving circuit.The main driving circuit consists of a series of IGBT protecting functions,which will be introduced in detail in chapter 3.The transformer in isolation ciruit is also designed,and the logic tructure of the driver chip is also built.Then,made the simulation above the modules with Saber and Pspcie,the correctness of the principle is proved.Finally,in order to make the driver board can effectively resist the interference among the signals in each layer,reduce the parasitic inductance,improve stability. The fifth chapter analysis of the layout and wiring requirements, Design an draw the six panels IGBT driver board with Allegro Cadence.Followed by the corresponding softwares,SI and PI simulation is made.The reliability of signal quality is verified,and the problem signal is optimize.The PCB resonance and the current density are simulated,the position of the resonance point is also optimized.At the end of the bench test,confirmed that the driver board can achieve the preset requirement.更多还原
